I learned early on to ‘fess up when you have done something wrong.” People appreciate it when you tell them up front that you goofed. That way the problem can be dealt with directly. Dee Ball was that way. Any time he wrecked a truck, he didn’t hesitate to tell his boss. So, even as a summer help I had developed this philosophy. Never be afraid to expose your blunders. It works out better in the long run.
One example of someone not following this philosophy was Curtis Love. As I mentioned in the post Power Plant Spider Wars and Bugs in the Basement, Curtis didn’t want to tell anyone that he had been bitten by a brown recluse for the third time because he was afraid of losing his job.

His philosophy came back to bite him a year and a half later when he was on the labor crew when he was the designated truck driver. I had moved on to the electric shop by this time.

He was backing up the crew cab around a corner under the Fly Ash hoppers up at the coalyard when the side of the crew cab came into contact with one of those yellow poles designed to protect the structure from rogue vehicles. Unfortunately. This created a dent in the side of the truck.

Curtis, already on probation. worried that he would be fired if he told anyone about this mishap, failed to tell Larry Riley about this incident. Larry, on the other hand, was standing in front of the Coalyard Maintenance shop (the labor crew home), and saw the entire incident. At that moment, he turned to one of the labor crew hands and said, “I hope Curtis comes over here and tells me about that.” Unfortunately, Curtis decided to act as if nothing had happened. This resulted in his termination. As much as I cared about Curtis, I must admit that the Power Plant scene was probably not the best location for his vocation.
I had seen Dee Ball do the same thing over and over again, and he always reported his accidents immediately. He was never punished for an accident, though, for a number of years, he was banned from driving a truck. You can read more about this in the post: Experiencing Maggots, Mud and Motor Vehicles with Dee Ball.
One day during the summer of 1984 just after lunch, 1A PA fan tripped (PA stands for Primary Air). When this happened, number one unit had to lower it’s output from over 500 Megawatts down to around 200. The trip indicator on the 6900 volt breaker said that it had been grounded. Being grounded means that one of the three phases of the motor or cable had made a circuit with the ground (or something that was grounded). The trip circuits shut the fan down so fast that it prevents an explosion and saves the fan from being destroyed.
Diana Lucas (later Diana Brien), Andy Tubbs and I were given the task of finding the ground and seeing what we could do to fix it. We unwired the motor, which was no easy task, because the motor is about the size of a large van, and about 10 times heavier.
This is about 1/2 the size of the PA fan motor which is 1000 horsepower
So, we spent the rest of the day unwiring the motor (in the rain), and unwiring the cable to the motor from the breaker in the main switchgear and testing both the motor and the cable with various instruments looking for the grounded wire or coil that caused the motor to trip. We used a large “Megger” on the motor. It’s called a Megger because it measures Mega-Ohms. So, it’s technically called a Mega-Ohm meter. Ohms is a measurement of resistance in an electrical circuit. We usually use a small hand cranked megger, that is similar to an old hand crank telephone that generates a high voltage (good for shocking fish in a lake to make them rise to the surface). In the case of the hand cranked Megger, it would generate 1,000 volts.
A Hand cranked Megger made by the same company, only newer than the ones we had
The Megger this size would have been useless with this large motor. Instead we used one that was electric, and you ran the voltage up over 10,000 volts and watched the mega-ohms over a period of 1/2 hour or so.
For the cables, we hooked up a Hypot (or Hipot). This stands for High Potential. Potential in this case is another word for “Voltage”. It would charge up and then you pressed a button and it would send a high voltage pulse down the cable, and if there is a weak spot in the insulation,The Hypot will find it. So, we hooked a Hypot up to the cable and tried to find the grounded wire. No luck.
After spending 4 hours looking for the grounded cable or motor, we found nothing. We spent another hour and a half putting the motor and the breaker back in service. The Fan was put back into operation and we went home. As I was walking out to the car with Bill Rivers, he told me, “I knew they weren’t going to find anything wrong with that fan.” He had a big grin on his face.
At first I thought he was just making an educated guess as Rivers was apt to do on many occasions (daily). It was raining and I could see where water may have been sucked into the motor or something and had momentarily grounded the motor. Just because we didn’t find anything didn’t mean that the breaker didn’t trip for no reason.
When we were in the car and on our way to Stillwater, Oklahoma with Yvonne Taylor and Rich Litzer, Bill explained that he knew why the motor tripped. He had been walking through the main switchgear with Mike Rose, and Mike, for no apparent reason other than curiosity, had opened up the bottom door to the breaker for 1A PA fan. He looked at it for a moment and then slammed the door shut. When he did this, the breaker tripped.
So, the ground relay happened to be the one that tripped. It might as well been an over-current or a low voltage trip. It just happened to trip the ground trip. Bill said that he told Mike that he should call the Shift Supervisor and let him know so they could restart the motor. Mike on the other hand told Bill that he was already on probation and was afraid of losing his job if he reported that he had slammed the door on the breaker and tripped the fan.
If there was ever a reason to call 911, it was then. All he had to do was tell them, “I accidentally tripped the PA fan when I bumped the breaker cabinet.” They would have told him to reset the flag, and they would have started the fan right back up. No questions asked… I’m sure of it. And they wouldn’t have lost their generating capacity for the remainder of the afternoon and we wouldn’t have spent 4 hours unwiring, testing and rewiring the motor in the rain with a plastic umbrella over our head.
Bill wasn’t about to tell on Mike. If Mike didn’t want to report it, Bill wasn’t going to say anything, and I understand that. I probably would have kept it to myself at the time if I was in Bill’s shoes (I’m just glad I wasn’t because I probably wouldn’t have been able to sleep soundly for the next year). But 30 years later, I might write about it in a Blog. Even though I wouldn’t have looked to Mike to teach me much about being an electrician (he was more of an Air Condition man anyway), I still loved the guy.
Mike died almost two years ago on May 29, 2011. He was from England and had lived in Canada for a time. He used to work on trains. Trains, even though they are diesel, are really electric. The Diesel engine really runs a generator that generates electricity that runs the train. I know that Mike was a good man at heart. He loved his family with all his heart. Here is a picture of the Limey:
Mike Rose. A fair plant electrician, but a great family man!
Ok. So I know what you are thinking…. There must be a story about myself in here somewhere. Well, you would be right. First of all. I always ‘fessed up to my mistakes, as my current manager at Dell knows well (yes. I still mess up after all these years). I told my current manager the other day that CLM was my middle name. (CLM means “Career Limiting Move”). So here is my power plant “mess up” story (well one of them):
In January 1986, I returned from my Honeymoon with my new wife Kelly when I found that we had hired a new electrician. Gary Wehunt was replacing Jim Stephenson who had left the plant on February 15, 1985, which is a story all it’s own. We had just started an overhaul on Unit 1.
I remember the first Monday I spent with Gary. It was January 6, 1986 and we were working on cleaning out the exciter house on the end of the main power generator with Diana Brien (formerly Diana Lucas). We were discussing salaries and Gary was surprised to find out that I was making more than he was. Well… I had been an electrician for over 2 years and had been promoted regularly…. so I didn’t think there was anything strange about it, except that I still looked like I was only about 18 years old (even though I was 25) and Gary was about 34. I had already been promoted 4 times and my salary had gone from $7.15 to over $12 an hour.
Anyway, when that first Wednesday rolled around, Since Gary and I were assigned to Substation Inspection that week, (Some later time I may go into the details of what “Substation Inspection” entails), but for now, let’s just stick with my “911 call.” It is enough to say that we were in the main plant substation relay house on Wdnesday January 8, 1986 at 9:00 am. One of our jobs was to call other substations and perform a test called a “Transfer Trip and Carrier Test”. We had called Woodring Substation (Woodring is a town in Oklahoma and we had a 345 KV line going there), and I was talking to the man in the substation on the other end of the phone line.
At the same time I was showing Gary just how experienced I was at being an electrician. People had told me that you had to be a plant electrician for 5 years before you really became a “first class” electrician. Well. Here I was at 2 years, and I thought I was so good that I could do anything by now…. — Yeah… right. I told the guy on the other end of the line as I turned a switch…. Amber light… Back to Blue…. and I wrote down the value on the meter (paperwork… oh yes…. it’s that important. Like A-1 sauce).
Then I reached for the second switch. I said, “Carrier test”, then turned the switch. The lights in the relay house went out and we were in the dark. I told the guy on the other end of the line….. “Well. That’s not supposed to happen.” Then as I let go of the switch and it returned to it’s normal position, the lights turned back on. Okay……
I wrote the numbers down from the meter and said goodbye to the other faceless substation man on the other end of the line that I talked to over 100 times, but never met in person. He sounded like a nice guy. Then I headed for the gray phone. I heard the Shift Supervisor paging Leroy Godfrey (The Electrical Supervisor) on line 2 (we had 5 Gray phone lines. The Gray Phone was our PA system).
When I picked up the line I heard Leroy pick up the phone and the Shift Supervisor tell Leroy that we just lost station power in the main substation and it had switched over to Auxiliary power. I immediately jumped in and said, “Jim (for Jim Padgett, the Shift Supervisor), I did that. I was performing a Carrier test with Woodring and the moment I performed the carrier test the lights went out.” Leroy chimed in by saying, “That wouldn’t cause you to lose station power.”
Well, in my ‘inexperienced’ plant electrician way, I responded, “Well. All I know is that when I turned the switch to perform the carrier test, the lights went out, and when I let go of the switch, the lights came back on.” Leroy reiterated, “That wouldn’t cause you to lose station power.” I replied with, “I’m just saying….” and left it at that. I had done my job. They knew I was out here. They knew I had called 911 right away. I explained what I was doing…. they could take it from there.
I had hoped that I had showed Gary upfront that it doesn’t hurt to report your mistakes (even though I hadn’t made one as far as I could tell), but I was 100% sure I had done something to cause the relay house to lose power. Though, I couldn’t figure out why.
After lunch, Bill Bennett, our A foreman came down to the shop to tell me that they figured out how the substation lost station power. He said that a road grader had been grating the road down by the Otoe-Missouri reservation (which is actually called “Windmill road” I guess because there is a windmill down that road somewhere), and had hit an electric pole and knocked it over and had killed the power to the substation.
Substation Power Interrupting Road Grader
It turned out that the substation relay house was fed by a substation down that road where we have a radio tower. So, think about this. The exact time that I turned that switch in the substation, a road grater 2 1/2 miles away hits a telephone pole accidentally and knocks it to the ground and kills the power to the substation at the exact same time that I am performing a transfer-trip and Carrier test with Woodring Substation, and the time it takes to switch to auxiliary power is the exact time it took me to let go of the switch.
Don’t tell me that was by accident. I will never believe it. I think it was for the soul purpose of teaching me a useful lesson or two. First….. don’t be afraid to tell someone when you do something wrong. Second…. If you think you have control over the things that happen to you in your life… well, think again…… Third….. God watches you every moment, and if you let him, he will guide you to do the right thing when the time comes. Oh, and Fourth: “Doesn’t God have a great sense of humor?”
God bless you all.

I had a similar thing happen to me, I was upgrading to shift foreman & system called to remove a tag in the switchyard & put the switch back to auto. The tag on the pistol grip was attached with a plastic zip tie & the previous operator had put it on real tight, as I was wrestling it off with my leatherman, the pliers slipped & I banged my elbow into the control panel, at that very instant there was a loud BANG as several 345 KV breakers opened simultaneously in the switchyard, I had the phone pinched between my shoulder & ear as I was wrestling with this switch & talking to the system control operator, he said a few bad words – gotta go – & hung up. The power plant lost all power & went in the black, I, of course was just sick in the pit of my stomach, after we got power restored, the plant back on etc. I called system back to see if they found the cause & fess up to causing the trip (I figured I must have caused a trip relay to close when I hit the panel) – anyway a crane at a plant down the road had got it’s boom tangled in the power line & went to ground – AT PRECISELY THE INSTANT MY ELBOW SLIPPED & HIT THE PANEL!!

CLM: I can relate.
My first boss 30 years ago once told me he was going to officially nickname me “I’m sorry” (and make me wear it for a name badge) if I said it one more time.
Hey, there’s worse things.

I had not thought about Mike Rose in years. He was a good guy to work with, now Rivers was a different story!!!
Sub checks, I used to love to do sub checks. I performed pilot wire & transfer trip checks for years. I hated it when they went to being done by automation.
Thanks for bringing back old memories.
Power Plant Millennium Experience
I suppose most people remember where they were New Year’s Eve at midnight on Saturday, January 1, 2000. That is a night I will never forget. Some people were hiding in self-made bunkers waiting for the end of the world which never came, others were celebrating at home with their families and friends. I suppose some people went on with their lives as if nothing was different that night. Not my family. My wife and two children spent the night at the Power Plant waiting to see if all of the testing we had performed the last two years had covered all possible failures of the Y2K scare.
A small group of Power Plant Men had been chosen to attend a party with our families in the main conference room at the Power Plant. All the food and drinks were supplied by the company. Our Plant Manager, Bill Green was there. Children were given the opportunity to rest in some other room as it reached their bedtimes.
Two years before this fateful night, the company was in full swing preparing for the Y2K computer disaster that had been foretold by those who knew that many computer systems only used two digits for the year instead of all four. so, when the year 2000 rolled around, it would suddenly show up in the computer as 00, which didn’t compute as a year in some systems. After all, you can’t divide something by 00. Suddenly, the time between events that just happened before midnight and those that happen just after midnight are 100 years apart in the wrong direction.
The coal-fired Power Plant in North Central Oklahoma was completed in 1979 and 1980, so, my first thought was that by that time, computers were far enough along to know better. The Instrument and Controls Power Plant Men along with the Plant Engineers decided that the best way to check their systems was to change the clocks on the computers one at a time to just before midnight on New Year’s Eve and see what happens.
I thought that was a pretty ingenious way to go about testing the computer systems. By changing the clock on each system one at a time to New Year’s Eve and watching it roll over to the new Millennium, you learn right away if you have a problem, and you have contained the disaster to one system at a time while you test it. By doing this, it turned out that there was a problem with one system at the Co-Generation plant at the Continental Oil Refinery 20 miles north of the plant.
I wrote a post about the Co-Generation Plant in a previous post: “What Coal-fired Power Plant Electricians Are Doing at an Oil Refinery“. When it was discovered that the computer at the Conoco Oil Refinery Power Plant would crash on New Year’s Eve, it was decided that we would just roll the clock back to 1950 (or so), and we wouldn’t have to worry about it for another 50 years. The thought was that by that time, this computer would be replaced.
This was the original thought which caused the Y2K problem in the first place. No one thought in the 1960’s that their computer systems would still be operating when the year 2000 came around, so they didn’t bother to use four digits for the year. Disk space was expensive at that time, and anything that could save a few bytes was considered an improvement instead of a bug.
My wife wasn’t too pleased when I told her where we were going to spend New Year’s Eve when Y2K rolled around, but then again, where would you rather be if a worldwide disaster happened and the electricity shutdown across the country? I would think the Power Plant would be the best place. You could at least say, “I was in the actual Control Room at a Power Plant watching them throw the switch and light up Oklahoma City!” Besides, we usually spent New Year’s Eve quietly at home with our kids.
Even though we were fairly certain everything had been accounted for, it was the unknown computer system sitting out there that no one had thought about that might shut everything down. Some system in a relay house in a substation, or some terrorist attack. So, there we sat watching the New Year roll in on a big screen TV at one end of the break room. Children’s movies were being shown most of the evening to keep the young occupied while we waited.
I thought that Jim Arnold, the Supervisor over the Maintenance Department, wanted me in the break room at the Power Plant so that he could keep an eye on me to make sure I wasn’t going to be causing trouble that night. Jim never really trusted me…. I suppose that was because strange things would happen when I was around. Of course, I would never do anything that would jeopardize the operation of the Power Plant, but that didn’t stop me from keeping Jim guessing.
No. Not really. I was there because I had a way with computers. I was the computer go to person at the plant, and if anything happened to any of them, I would probably be the person that could whisper it back into service. Also, if for some reason the Generators tripped, I was a switchman that could open and close switches in the substation and start the precipitator back up and run up to the top of the boiler if the boiler elevator broke down and get it started back up.
Except for my natural affinity for computers, any of the electricians in the Power Plant could do all those other things. I think there was just a little “prejudice” left over about me from when Bill Bennett our past A foreman used to say, “Let Kevin do it. He doesn’t mind getting dirty” (or…. he likes to climb the boiler, or…. he likes confined spaces, or… Kevin likes to stay up at all hours of the night working on things… I could go on… that was Bill’s response when someone asked him who should do the really grimy jobs — of course… to some degree…. he was usually right).
I was actually a little proud to be told that I was going to have to spend New Year’s Eve at the Power Plant. I had almost 17 years of experience as a Power Plant Electrician at that time, and I felt very comfortable working on any piece of equipment in the plant. If it was something I had never worked on before, then I would quickly learn how it worked… As I said, all the electricians in the plant were the same way. It was our way of life.
At 11:00 pm Central Time, we watched as the ball dropped in Time Square in New York City. The 10 or so Power Plant Men with their families sat in anticipation waiting…. and waiting… to see if the lights went out in New York…. Of course you know now that nothing happened, but we were ready to jump into a crisis mode if there were any reports of power failures across the country.
You see…. The electric grid on the east side of the Rocky Mountains is all connected together. If the power grid were to go down in one area, it could try dragging down the rest of the country. If protective relays in substations across the country don’t operate flawlessly, then a blackout occurs in a larger area than just one particular area covered by one electric company.
When relays operate properly, a blackout is contained in the smallest area possible. There was only one problem…. Breakers in substations are now controlled by remote computer systems. If those systems began to act erratic, then the country could have a problem. This did not happen that night.
There was a contract worker in the engineering department at our plant who was at his home in the country during this time hunkered down in a bunker waiting for the end of the world as was foretold by the minister of his church. He had purchased a large supply of food and water and had piled them up in his shelter along with a portable generator. He and his family waited out the end of the world that night waiting for the rapture. He told me about that a few months later. He was rather disappointed that the world hadn’t ended like it was supposed to. He was so prepared for it.
After 11 pm rolled around and there was no disaster on the east coast, things lightened up a bit. I decided to take my son and daughter on a night tour of the plant. So, we walked over to the control room where they could look at the control panels with all of the the lights and alarms. Here is a picture of Jim Cave and Allen Moore standing in front of the Unit 1 Control Panel:
Jim Cave with Allen Moore
Then I took each of them up to the top of the Boiler where you could look out over the lake at night from a view 250 feet high. The Power Plant becomes a magical world at night, with the rumbling sounds from the boiler, the quiet hissing of steam muffled by the night. The lights shining through the metal structure and open grating floors.
From the top of the boiler, you could look south and see the night lights from Stillwater, Pawnee and Perry. Looking north, you could see Ponca City and the Oil Refinery at Conoco (later Phillips). The only structure taller than the boilers are the smoke stacks. There was always a special quality about the plant at night that is hard to put your finger on. A sort of silence in a world of noise. It is like a large ship on the ocean. In a world of its own.
Power Plant at sunset across the lake
We returned to the break room 20 minutes before midnight, where our plant manager Bill Green and Jim Arnold tested their radios with the Control Room to make sure we were all in contact with each other. I had carried my tool bucket up to the break room in case I needed to dash off somewhere in a hurry.
This is an actual picture of my tool bucket
We felt confident by this time that a disaster was not going to happen when the clock rolled over to midnight. When the countdown happened, and the 5, 4, 3, 2, 1 counted down, We cheered “Happy New Year!” and hugged one another. I think both of my children had dozed off by this point.
Bill Green called the control room. The word came back that everything was business as usual. Nothing out of the ordinary. We waited around another hour just to make sure that nothing had shutdown. By 1:00 am on January 1, 2000, Bill Green gave us the (Bill) Green Light. We were all free to return to our homes.
I gathered up my two children and my wife Kelly, and we drove the 25 miles back home to the comfort of our own beds. When we went to bed early that morning after I had climbed into bed, I reached over and turned off the light on my nightstand. When the light went out, it was because I had decided to turn it off. Not because the world had suddenly come to an end. A new Millennium had just begun.

If there was ever a reason to call 911, it was then. All he had to do was tell them, “I accidentally tripped the PA fan when I bumped the breaker cabinet.” They would have told him to reset the flag, and they would have started the fan right back up. No questions asked… I’m sure of it. And they wouldn’t have lost their generating capacity for the remainder of the afternoon and we wouldn’t have spent 4 hours unwiring, testing and rewiring the motor in the rain with a plastic umbrella over our head.
Bill wasn’t about to tell on Mike. If Mike didn’t want to report it, Bill wasn’t going to say anything, and I understand that. I probably would have kept it to myself at the time if I was in Bill’s shoes (I’m just glad I wasn’t because I probably wouldn’t have been able to sleep soundly for the next year). But 30 years later, I might write about it in a Blog. Even though I wouldn’t have looked to Mike to teach me much about being an electrician (he was more of an Air Condition man anyway), I still loved the guy.
Mike died almost two years ago on May 29, 2011. He was from England and had lived in Canada for a time. He used to work on trains. Trains, even though they are diesel, are really electric. The Diesel engine really runs a generator that generates electricity that runs the train. I know that Mike was a good man at heart. He loved his family with all his heart. Here is a picture of the Limey:
Mike Rose. A fair plant electrician, but a great family man!
Ok. So I know what you are thinking…. There must be a story about myself in here somewhere. Well, you would be right. First of all. I always ‘fessed up to my mistakes, as my current manager at Dell knows well (yes. I still mess up after all these years). I told my current manager the other day that CLM was my middle name. (CLM means “Career Limiting Move”). So here is my power plant “mess up” story (well one of them):
In January 1986, I returned from my Honeymoon with my new wife Kelly when I found that we had hired a new electrician. Gary Wehunt was replacing Jim Stephenson who had left the plant on February 15, 1985, which is a story all it’s own. We had just started an overhaul on Unit 1.
I remember the first Monday I spent with Gary. It was January 6, 1986 and we were working on cleaning out the exciter house on the end of the main power generator with Diana Brien (formerly Diana Lucas). We were discussing salaries and Gary was surprised to find out that I was making more than he was. Well… I had been an electrician for over 2 years and had been promoted regularly…. so I didn’t think there was anything strange about it, except that I still looked like I was only about 18 years old (even though I was 25) and Gary was about 34. I had already been promoted 4 times and my salary had gone from $7.15 to over $12 an hour.
Anyway, when that first Friday rolled around, Gary and I were assigned to Substation Inspection. Some later time I may go into the details of what “Substation Inspection” entails, but for now, let’s just stick with my “911 call.” It is enough to say that we were in the main plant substation relay house on Friday January 10, 1986 at 9:00 am. One of our jobs was to call other substations and perform a test called a “Transfer Trip and Carrier Test”. We had called Woodring Substation (Woodring is a town in Oklahoma and we had a 345 KV line going there), and I was talking to the man in the substation on the other end of the phone line.
At the same time I was showing Gary just how experienced I was at being an electrician. People had told me that you had to be a plant electrician for 5 years before you really became a “first class” electrician. Well. Here I was at 2 years, and I thought I was so good that I could do anything by now…. — Yeah… right. I told the guy on the other end of the line as I turned a switch…. Amber light… Back to Blue…. and I wrote down the value on the meter (paperwork… oh yes…. it’s that important. Like A-1 sauce).
Then I reached for the second switch. I said, “Carrier test”, then turned the switch. The lights in the relay house went out and we were in the dark. I told the guy on the other end of the line….. “Well. That’s not supposed to happen.” Then as I let go of the switch and it returned to it’s normal position, the lights turned back on. Okay……
I wrote the numbers down from the meter and said goodbye to the other faceless substation man on the other end of the line that I talked to over 100 times, but never met in person. He sounded like a nice guy. Then I headed for the gray phone. I heard the Shift Supervisor paging Leroy Godfrey (The Electrical Supervisor) on line 2 (we had 5 Gray phone lines. The Gray Phone was our PA system).
When I picked up the line I heard Leroy pick up the phone and the Shift Supervisor tell Leroy that we just lost station power in the main substation and it had switched over to Auxiliary power. I immediately jumped in and said, “Jim (for Jim Padgett, the Shift Supervisor), I did that. I was performing a Carrier test with Woodring and the moment I performed the carrier test the lights went out.” Leroy chimed in by saying, “That wouldn’t cause you to lose station power.”
Well, in my ‘inexperienced’ plant electrician way, I responded, “Well. All I know is that when I turned the switch to perform the carrier test, the lights went out, and when I let go of the switch, the lights came back on.” Leroy reiterated, “That wouldn’t cause you to lose station power.” I replied with, “I’m just saying….” and left it at that. I had done my job. They knew I was out here. They knew I had called 911 right away. I explained what I was doing…. they could take it from there.
I had hoped that I had showed Gary upfront that it doesn’t hurt to report your mistakes (even though I hadn’t made one as far as I could tell), but I was 100% sure I had done something to cause the relay house to lose power. Though, I couldn’t figure out why.
After lunch, Bill Bennett, our A foreman came down to the shop to tell me that they figured out how the substation lost station power. He said that a road grader had been grating the road down by the Otoe-Missouri reservation (which is actually called “Windmill road” I guess because there is a windmill down that road somewhere), and had hit an electric pole and knocked it over and had killed the power to the substation.
Substation Power Interrupting Road Grader
It turned out that the substation relay house was fed by a substation down that road where we have a radio tower. So, think about this. The exact time that I turned that switch in the substation, a road grater 2 1/2 miles away hits a telephone pole accidentally and knocks it to the ground and kills the power to the substation at the exact same time that I am performing a transfer-trip and Carrier test with Woodring Substation, and the time it takes to switch to auxiliary power is the exact time it took me to let go of the switch.
Don’t tell me that was by accident. I will never believe it. I think it was for the soul purpose of teaching me a useful lesson or two. First….. don’t be afraid to tell someone when you do something wrong. Second…. If you think you have control over the things that happen to you in your life… well, think again…… Third….. God watches you every moment, and if you let him, he will guide you to do the right thing when the time comes.
God bless you all.

I had a similar thing happen to me, I was upgrading to shift foreman & system called to remove a tag in the switchyard & put the switch back to auto. The tag on the pistol grip was attached with a plastic zip tie & the previous operator had put it on real tight, as I was wrestling it off with my leatherman, the pliers slipped & I banged my elbow into the control panel, at that very instant there was a loud BANG as several 345 KV breakers opened simultaniously in the swithyard, I had the phone pinched between my shoulder & ear as I was wrestling with this switch & talking to the system control operator, he said a few bad words – gotta go – & hung up. The power plant lost all power & went in the black, I, of course was just sick in the pit of my stomach, after we got power restored, the plant back on etc. I called system back to see if they found the cause & fess up to causing the trip (I figured I must have caused a trip relay to close when I hit the panel) – anyway a crane at a plant down the road had got it’s boom tangled in the power line & went to ground – AT PRECISELY THE INSTANT MY ELBOW SLIPPED & HIT THE PANEL!!

CLM: I can relate.
My first boss 30 years ago once told me he was going to officially nickname me “I’m sorry” (and make me wear it for a name badge) if I said it one more time.
Hey, there’s worse things.

I had not thought about Mike Rose in years. He was a good guy to work with, now Rivers was a different story!!!
Sub checks, I used to love to do sub checks. I performed pilot wire & transfer trip checks for years. I hated it when they went to being done by automation.
Thanks for bringing back old memories.
Power Plant Millennium Experience
I suppose most people remember where they were New Year’s Eve at midnight on Saturday, January 1, 2000. That is a night I will never forget. Some people were hiding in self-made bunkers waiting for the end of the world which never came, others were celebrating at home with their families and friends. I suppose some people went on with their lives as if nothing was different that night. Not my family. My wife and two children spent the night at the Power Plant waiting to see if all of the testing we had performed the last two years had covered all possible failures of the Y2K scare.
A small group of Power Plant Men had been chosen to attend a party with our families in the main conference room at the Power Plant. All the food and drinks were supplied by the company. Our Plant Manager, Bill Green was there. Children were given the opportunity to rest in some other room as it reached their bedtimes.
Two years before this fateful night, the company was in full swing preparing for the Y2K computer disaster that had been foretold by those who knew that many computer systems only used two digits for the year instead of all four. so, when the year 2000 rolled around, it would suddenly show up in the computer as 00, which didn’t compute as a year in some systems. After all, you can’t divide something by 00. Suddenly, the time between events that just happened before midnight and those that happen just after midnight are 100 years apart in the wrong direction.
The coal-fired Power Plant in North Central Oklahoma was completed in 1979 and 1980, so, my first thought was that by that time, computers were far enough along to know better. The Instrument and Controls Power Plant Men along with the Plant Engineers decided that the best way to check their systems was to change the clocks on the computers one at a time to just before midnight on New Year’s Eve and see what happens.
I thought that was a pretty ingenious way to go about testing the computer systems. By changing the clock on each system one at a time to New Year’s Eve and watching it roll over to the new Millennium, you learn right away if you have a problem, and you have contained the disaster to one system at a time while you test it. By doing this, it turned out that there was a problem with one system at the Co-Generation plant at the Continental Oil Refinery 20 miles north of the plant.
I wrote a post about the Co-Generation Plant in a previous post: “What Coal-fired Power Plant Electricians Are Doing at an Oil Refinery“. When it was discovered that the computer at the Conoco Oil Refinery Power Plant would crash on New Year’s Eve, it was decided that we would just roll the clock back to 1950 (or so), and we wouldn’t have to worry about it for another 50 years. The thought was that by that time, this computer would be replaced.
This was the original thought which caused the Y2K problem in the first place. No one thought in the 1960’s that their computer systems would still be operating when the year 2000 came around, so they didn’t bother to use four digits for the year. Disk space was expensive at that time, and anything that could save a few bytes was considered an improvement instead of a bug.
My wife wasn’t too pleased when I told her where we were going to spend New Year’s Eve when Y2K rolled around, but then again, where would you rather be if a worldwide disaster happened and the electricity shutdown across the country? I would think the Power Plant would be the best place. You could at least say, “I was in the actual Control Room at a Power Plant watching them throw the switch and light up Oklahoma City!” Besides, we usually spent New Year’s Eve quietly at home with our kids.
Even though we were fairly certain everything had been accounted for, it was the unknown computer system sitting out there that no one had thought about that might shut everything down. Some system in a relay house in a substation, or some terrorist attack. So, there we sat watching the New Year roll in on a big screen TV at one end of the break room. Children’s movies were being shown most of the evening to keep the young occupied while we waited.
I thought that Jim Arnold, the Supervisor over the Maintenance Department, wanted me in the break room at the Power Plant so that he could keep an eye on me to make sure I wasn’t going to be causing trouble that night. Jim never really trusted me…. I suppose that was because strange things would happen when I was around. Of course, I would never do anything that would jeopardize the operation of the Power Plant, but that didn’t stop me from keeping Jim guessing.
No. Not really. I was there because I had a way with computers. I was the computer go to person at the plant, and if anything happened to any of them, I would probably be the person that could whisper it back into service. Also, if for some reason the Generators tripped, I was a switchman that could open and close switches in the substation and start the precipitator back up and run up to the top of the boiler if the boiler elevator broke down and get it started back up.
Except for my natural affinity for computers, any of the electricians in the Power Plant could do all those other things. I think there was just a little “prejudice” left over about me from when Bill Bennett our past A foreman used to say, “Let Kevin do it. He doesn’t mind getting dirty” (or…. he likes to climb the boiler, or…. he likes confined spaces, or… Kevin likes to stay up at all hours of the night working on things… I could go on… that was Bill’s response when someone asked him who should do the really grimy jobs — of course… to some degree…. he was usually right).
I was actually a little proud to be told that I was going to have to spend New Year’s Eve at the Power Plant. I had almost 17 years of experience as a Power Plant Electrician at that time, and I felt very comfortable working on any piece of equipment in the plant. If it was something I had never worked on before, then I would quickly learn how it worked… As I said, all the electricians in the plant were the same way. It was our way of life.
At 11:00 pm Central Time, we watched as the ball dropped in Time Square in New York City. The 10 or so Power Plant Men with their families sat in anticipation waiting…. and waiting… to see if the lights went out in New York…. Of course you know now that nothing happened, but we were ready to jump into a crisis mode if there were any reports of power failures across the country.
You see…. The electric grid on the east side of the Rocky Mountains is all connected together. If the power grid were to go down in one area, it could try dragging down the rest of the country. If protective relays in substations across the country don’t operate flawlessly, then a blackout occurs in a larger area than just one particular area covered by one electric company.
When relays operate properly, a blackout is contained in the smallest area possible. There was only one problem…. Breakers in substations are now controlled by remote computer systems. If those systems began to act erratic, then the country could have a problem. This did not happen that night.
There was a contract worker in the engineering department at our plant who was at his home in the country during this time hunkered down in a bunker waiting for the end of the world as was foretold by the minister of this church. He had purchased a large supply of food and water and had piled them up in his shelter along with a portable generator. He and his family waited out the end of the world that night waiting for the rapture. He told me about that a few months later. He was rather disappointed that the world hadn’t ended like it was supposed to. He was so prepared for it.
After 11 pm rolled around and there was no disaster on the east coast, things lightened up a bit. I decided to take my son and daughter on a night tour of the plant. So, we walked over to the control room where they could look at the control panels with all of the the lights and alarms. Here is a picture of Jim Cave and Allen Moore standing in front of the Unit 1 Control Panel:
Jim Cave with Allen Moore
Then I took each of them up to the top of the Boiler where you could look out over the lake at night from a view 250 feet high. The Power Plant becomes a magical world at night, with the rumbling sounds from the boiler, the quiet hissing of steam muffled by the night. The lights shining through the metal structure and open grating floors.
From the top of the boiler, you could look south and see the night lights from Stillwater, Pawnee and Perry. Looking north, you could see Ponca City and the Oil Refinery at Conoco (later Phillips). The only structure taller than the boilers are the smoke stacks. There was always a special quality about the plant at night that is hard to put your finger on. A sort of silence in a world of noise. It is like a large ship on the ocean. In a world of its own.
Power Plant at sunset across the lake
We returned to the break room 20 minutes before midnight, where our plant manager Bill Green and Jim Arnold tested their radios with the Control Room to make sure we were all in contact with each other. I had carried my tool bucket up to the break room in case I needed to dash off somewhere in a hurry.
This is an actual picture of my tool bucket
We felt confident by this time that a disaster was not going to happen when the clock rolled over to midnight. When the countdown happened, and the 5, 4, 3, 2, 1 counted down, We cheered “Happy New Year!” and hugged one another. I think both of my children had dozed off by this point.
Bill Green called the control room. The word came back that everything was business as usual. Nothing out of the ordinary. We waited around another hour just to make sure that nothing had shutdown. By 1:00 am on January 1, 2000, Bill Green gave us the Green Light. We were all free to return to our homes.
I gathered up my two children and my wife Kelly, and we drove the 25 miles back home to the comfort of our own beds. When we went to bed early that morning after I had climbed into bed, I reached over and turned off the light on my nightstand. When the light went out, it was because I had decided to turn it off. Not because the world had suddenly come to an end. A new Millennium had just begun.

When is the appropriate time to call 911? Calling 911 in the Power Plant is when you call the Shift Supervisor to report something important. As Randy Dailey, our Safety Trainer extraordinaire, always taught us, first tap the person on the shoulder and say, “Are you all right?” Then you point you finger at someone and say, “Call 911!” That’s called “Activating the EMS” (Emergency Medical System). Besides medical emergencies, there are other reasons to call the Shift Supervisor.
I learned early on to ‘fess up when you have done something wrong.” People appreciate it when you tell them up front that you goofed. That way the problem can be dealt with directly. Dee Ball was that way. Any time he wrecked a truck, he didn’t hesitate to tell his boss. So, even as a summer help I had developed this philosophy. Never be afraid to expose your blunders. It works out better in the long run.
One example of someone not following this philosoply was Curtis Love. As I mentioned in the post Power Plant Spider Wars and Bugs in the Basement, Curtis didn’t want to tell anyone that he had been bitten by a brown recluse for the third time because he was afraid of losing his job.
The Oklahoma house spider — The Brown Recluse
His philosophy came back to bite him a year and a half later when he was on the labor crew when he was the designated truck driver. I had moved on to the electric shop by this time.
A red crew cab like this only the bed of the truck was longer
He was backing up the crew cab around a corner under the Fly Ash hoppers up at the coalyard when the side of the crew cab came into contact with one of those yellow poles designed to protect the structure from rogue vehicles. Unfortunately. This created a dent in the side of the truck.
An example of yellow poles protecting an area
Curtis, already on probation. worried that he would be fired if he told anyone about this mishap, failed to tell Larry Riley about this incident. Larry, on the other hand, was standing in front of the Coalyard Maintenance shop (the labor crew home), and saw the entire incident. At that moment, he turned to one of the labor crew hands and said, “I hope Curtis comes over here and tells me about that.” Unfortunately, Curtis decided to act as if nothing had happened. This resulted in his termination. As much as I cared about Curtis, I must admit that the Power Plant scene was probably not the best location for his vocation.
I had seen Dee Ball do the same thing over and over again, and he always reported his accidents immediately. He was never punished for an accident, though, for a number of years, he was banned from driving a truck. You can read more about this in the post: Experiencing Maggots, Mud and Motor Vehicles with Dee Ball.
One day during the summer of 1984 just after lunch, 1A PA fan tripped (PA stands for Primary Air). When this happened, number one unit had to lower it’s output from over 500 Megawatts down to around 200. The trip indicator on the 6900 volt breaker said that it had been grounded. Being grounded means that one of the three phases of the motor or cable had made a circuit with the ground (or something that was grounded). The trip circuits shut the fan down so fast that it prevents an explosion and saves the fan from being destroyed.
Diana Lucas (later Diana Brien), Andy Tubbs and I were given the task of finding the ground and seeing what we could do to fix it. We unwired the motor, which was no easy task, because the motor is about the size of a large van, and about 10 times heavier.
This is about 1/2 the size of the PA fan motor which is 1000 horsepower
So, we spent the rest of the day unwiring the motor (in the rain), and unwiring the cable to the motor from the breaker in the main switchgear and testing both the motor and the cable with various instruments looking for the grounded wire or coil that caused the motor to trip. We used a large “Megger” on the motor. It’s called a Megger because it measures Mega-Ohms. So, it’s technically called a Mega-Ohm meter. Ohms is a measurement of resistance in an electrical circuit. We usually use a small hand cranked megger, that is similar to an old hand crank telephone that generates a high voltage (good for shocking fish in a lake to make them rise to the surface). In the case of the hand cranked Megger, it would generate 1,000 volts.
A Hand cranked Megger made by the same company, only newer than the ones we had
The Megger this size would have been useless with this large motor. Instead we used one that was electric, and you ran the voltage up over 10,000 volts and watched the mega-ohms over a period of 1/2 hour or so.
For the cables, we hooked up a Hypot (or Hipot). This stands for High Potential. Potential in this case is another word for “Voltage”. It would charge up and then you pressed a button and it would send a high voltage pulse down the cable, and if there is a weak spot in the insulation,The Hypot will find it. So, we hooked a Hypot up to the cable and tried to find the grounded wire. No luck.
After spending 4 hours looking for the grounded cable or motor, we found nothing. We spent another hour and a half putting the motor and the breaker back in service. The Fan was put back into operation and we went home. As I was walking out to the car with Bill Rivers, he told me, “I knew they weren’t going to find anything wrong with that fan.” He had a big grin on his face.
At first I thought he was just making an educated guess as Rivers was apt to do on many occasions (daily). It was raining and I could see where water may have been sucked into the motor or something and had momentarily grounded the motor. Just because we didn’t find anything didn’t mean that the breaker didn’t trip for no reason.
When we were in the car and on our way to Stillwater, Oklahoma with Yvonne Taylor and Rich Litzer, Bill explained that he knew why the motor tripped. He had been walking through the main switchgear with Mike Rose, and Mike, for no apparent reason other than curiosity, had opened up the bottom door to the breaker for 1A PA fan. He looked at it for a moment and then slammed the door shut. When he did this, the breaker tripped.
So, the ground relay happened to be the one that tripped. It might as well been an over-current or a low voltage trip. It just happened to trip the ground trip. Bill said that he told Mike that he should call the Shift Supervisor and let him know so they could restart the motor. Mike on the other hand told Bill that he was already on probation and was afraid of losing his job if he reported that he had slammed the door on the breaker and tripped the fan.
If there was ever a reason to call 911, it was then. All he had to do was tell them, “I accidentally tripped the PA fan when I bumped the breaker cabinet.” They would have told him to reset the flag, and they would have started the fan right back up. No questions asked… I’m sure of it. And they wouldn’t have lost their generating capacity for the remainder of the afternoon and we wouldn’t have spent 4 hours unwiring, testing and rewiring the motor in the rain with a plastic umbrella over our head.
Bill wasn’t about to tell on Mike. If Mike didn’t want to report it, Bill wasn’t going to say anything, and I understand that. I probably would have kept it to myself at the time if I was in Bill’s shoes (I’m just glad I wasn’t because I probably wouldn’t have been able to sleep soundly for the next year). But 30 years later, I might write about it in a Blog. Even though I wouldn’t have looked to Mike to teach me much about being an electrician (he was more of an Air Condition man anyway), I still loved the guy.
Mike died almost two years ago on May 29, 2011. He was from England and had lived in Canada for a time. He used to work on trains. Trains, even though they are diesel, are really electric. The Diesel engine really runs a generator that generates electricity that runs the train. I know that Mike was a good man at heart. He loved his family with all his heart. Here is a picture of the Limey:
Mike Rose. A fair plant electrician, but a great family man!
Ok. So I know what you are thinking…. There must be a story about myself in here somewhere. Well, you would be right. First of all. I always ‘fessed up to my mistakes, as my current manager at Dell knows well (yes. I still mess up after all these years). I told my current manager the other day that CLM was my middle name. (CLM means “Career Limiting Move”). So here is my power plant “mess up” story (well one of them):
In January 1986, I returned from my Honeymoon with my new wife Kelly when I found that we had hired a new electrician. Gsry Wehunt was replacing Jim Stephenson who had left the plant on February 15, 1985, which is a story all it’s own. We had just started an overhaul on Unit 1.
I remember the first Monday I spent with Gary. It was January 6, 1986 and we were working on cleaning out the exciter house on the end of the main power generator with Diana Brien (formerly Diana Lucas). We were discussing salaries and Gary was surprised to find out that I was making more than he was. Well… I had been an electrician for over 2 years and had been promoted regularly…. so I didn’t think there was anything strange about it, except that I still looked like I was only about 18 years old (even though I was 25) and Gary was about 34. I had already been promoted 4 times and my salary had gone from $7.15 to over $12 an hour.
Anyway, when that first Friday rolled around, Gary and I were assigned to Substation Inspection. Some later time I may go into the details of what “Substation Inspection” entails, but for now, let’s just stick with my “911 call.” It is enough to say that we were in the main plant substation relay house on Friday January 10, 1986 at 9:00 am. One of our jobs was to call other substations and perform a test called a “Transfer Trip and Carrier Test”. We had called Woodring Substation (Woodring is a town in Oklahoma and we had a 345 KV line going there), and I was talking to the man in the substation on the other end of the phone line.
At the same time I was showing Gary just how experienced I was at being an electrician. People had told me that you had to be a plant electrician for 5 years before you really became a “first class” electrician. Well. Here I was at 2 years, and I thought I was so good that I could do anything by now…. — Yeah… right. I told the guy on the other end of the line as I turned a switch…. Amber light… Back to Blue…. and I wrote down the value on the meter (paperwork… oh yes…. it’s that important. Like A-1 sauce).
Then I reached for the second switch. I said, “Carrier test”, then turned the switch. The lights in the relay house went out and we were in the dark. I told the guy on the other end of the line….. “Well. That’s not supposed to happen.” Then as I let go of the switch and it returned to it’s normal position, the lights turned back on. Okay……
I wrote the numbers down from the meter and said goodbye to the other faceless substation man on the other end of the line that I talked to over 100 times, but never met in person. He sounded like a nice guy. Then I headed for the gray phone. I heard the Shift Supervisor paging Leroy Godfrey (The Electrical Supervisor) on line 2 (we had 5 Gray phone lines. The Gray Phone was our PA system).
When I picked up the line I heard Leroy pick up the phone and the Shift Supervisor tell Leroy that we just lost station power in the main substation and it had switched over to Auxiliary power. I immediately jumped in and said, “Jim (for Jim Padgett, the Shift Supervisor), I did that. I was performing a Carrier test with Woodring and the moment I performed the carrier test the lights went out.” Leroy chimed in by saying, “That wouldn’t cause you to lose station power.”
Well, in my ‘inexperienced’ plant electrician way, I responded, “Well. All I know is that when I turned the switch to perform the carrier test, the lights went out, and when I let go of the switch, the lights came back on.” Leroy reiterated, “That wouldn’t cause you to lose station power.” I replied with, “I’m just saying….” and left it at that. I had done my job. They knew I was out here. They knew I had called 911 right away. I explained what I was doing…. they could take it from there.
I had hoped that I had showed Gary upfront that it doesn’t hurt to report your mistakes (even though I hadn’t made one as far as I could tell), but I was 100% sure I had done something to cause the relay house to lose power. Though, I couldn’t figure out why.
After lunch, Bill Bennett, our A foreman came down to the shop to tell me that they figured out how the substation lost station power. He said that a road grader had been grating the road down by the Otoe-Missouri reservation (which is actually called “Windmill road” I guess because there is a windmill down that road somewhere), and had hit an electric pole and knocked it over and had killed the power to the substation.
Substation Power Interrupting Road Grader
It turned out that the substation relay house was fed by a substation down that road where we have a radio tower. So, think about this. The exact time that I turned that switch in the substation, a road grater 2 1/2 miles away hits a telephone pole accidentally and knocks it to the ground and kills the power to the substation at the exact same time that I am performing a transfer-trip and Carrier test with Woodring Substation, and the time it takes to switch to auxiliary power is the exact time it took me to let go of the switch.
Don’t tell me that was by accident. I will never believe it. I think it was for the soul purpose of teaching me a useful lesson or two. First….. don’t be afraid to tell someone when you do something wrong. Second…. If you think you have control over the things that happen to you in your life… well, think again…… Third….. God watches you every moment, and if you let him, he will guide you to do the right thing when the time comes.
God bless you all.

I had a similar thing happen to me, I was upgrading to shift foreman & system called to remove a tag in the switchyard & put the switch back to auto. The tag on the pistol grip was attached with a plastic zip tie & the previous operator had put it on real tight, as I was wrestling it off with my leatherman, the pliers slipped & I banged my elbow into the control panel, at that very instant there was a loud BANG as several 345 KV breakers opened simultaniously in the swithyard, I had the phone pinched between my shoulder & ear as I was wrestling with this switch & talking to the system control operator, he said a few bad words – gotta go – & hung up. The power plant lost all power & went in the black, I, of course was just sick in the pit of my stomach, after we got power restored, the plant back on etc. I called system back to see if they found the cause & fess up to causing the trip (I figured I must have caused a trip relay to close when I hit the panel) – anyway a crane at a plant down the road had got it’s boom tangled in the power line & went to ground – AT PRECISELY THE INSTANT MY ELBOW SLIPPED & HIT THE PANEL!!

Dee Ball was that way. Any time he wrecked a truck, he didn’t hesitate to tell his boss. So, even as a summer help I had developed this philosophy. Never be afraid to expose your blunders. It works out better in the long run.
One example of someone not following this philosoply was Curtis Love. As I mentioned in the post Power Plant Spider Wars and Bugs in the Basement, Curtis didn’t want to tell anyone that he had been bitten by a brown recluse for the third time because he was afraid of losing his job.
The Oklahoma house spider — The Brown Recluse
His philosophy came back to bite him a year and a half later when he was on the labor crew when he was the designated truck driver. I had moved on to the electric shop by this time.
A red crew cab like this only the bed of the truck was longer
He was backing up the crew cab around a corner under the Fly Ash hoppers up at the coalyard when the side of the crew cab came into contact with one of those yellow poles designed to protect the structure from rogue vehicles. Unfortunately. This created a dent in the side of the truck.
An example of yellow poles protecting an area
Curtis, already on probation. worried that he would be fired if he told anyone about this mishap, failed to tell Larry Riley about this incident. Larry, on the other hand, was standing in front of the Coalyard Maintenance shop (the labor crew home), and saw the entire incident. At that moment, he turned to one of the labor crew hands and said, “I hope Curtis comes over here and tells me about that.” Unfortunately, Curtis decided to act as if nothing had happened. This resulted in his termination. As much as I cared about Curtis, I must admit that the Power Plant scene was probably not the best location for his vocation.
I had seen Dee Ball do the same thing over and over again, and he always reported his accidents immediately. He was never punished for an accident, though, for a number of years, he was banned from driving a truck. You can read more about this in the post: Experiencing Maggots, Mud and Motor Vehicles with Dee Ball.
One day during the summer of 1984 just after lunch, 1A PA fan tripped (PA stands for Primary Air). When this happened, number one unit had to lower it’s output from over 500 Megawatts down to around 200. The trip indicator on the 6900 volt breaker said that it had been grounded. Being grounded means that one of the three phases of the motor or cable had made a circuit with the ground (or something that was grounded). The trip circuits shut the fan down so fast that it prevents an explosion and saves the fan from being destroyed.
Diana Lucas (later Diana Brien), Andy Tubbs and I were given the task of finding the ground and seeing what we could do to fix it. We unwired the motor, which was no easy task, because the motor is about the size of a large van, and about 10 times heavier.
This is about 1/2 the size of the PA fan motor which is 1000 horsepower

We usually use a small hand cranked megger, that is similar to an old hand crank telephone that generates a high voltage (good for shocking fish in a lake to make them rise to the surface). In the case of the hand cranked Megger, it would generate 1,000 volts.
A Hand cranked Megger made by the same company, only newer than the ones we had
The Megger this size would have been useless with this large motor. Instead we used one that was electric, and you ran the voltage up over 10,000 volts and watched the mega-ohms over a period of 1/2 hour or so.
For the cables, we hooked up a Hypot (or Hipot). This stands for High Potential. Potential in this case is another word for “Voltage”. It would charge up and then you pressed a button and it would send a high voltage pulse down the cable, and if there is a weak spot in the insulation,The Hypot will find it. So, we hooked a Hypot up to the cable and tried to find the grounded wire. No luck.
After spending 4 hours looking for the grounded cable or motor, we found nothing. We spent another hour and a half putting the motor and the breaker back in service. The Fan was put back into operation and we went home. As I was walking out to the car with Bill Rivers, he told me, “I knew they weren’t going to find anything wrong with that fan.” He had a big grin on his face.
At first I thought he was just making an educated guess as Rivers was apt to do on many occasions (daily). It was raining and I could see where water may have been sucked into the motor or something and had momentarily grounded the motor. Just because we didn’t find anything didn’t mean that the breaker didn’t trip for no reason.
When we were in the car and on our way to Stillwater, Oklahoma with Yvonne Taylor and Rich Litzer, Bill explained that he knew why the motor tripped. He had been walking through the main switchgear with Mike Rose, and Mike, for no apparent reason other than curiosity, had opened up the bottom door to the breaker for 1A PA fan. He looked at it for a moment and then slammed the door shut. When he did this, the breaker tripped.
So, the ground relay happened to be the one that tripped. It might as well been an over-current or a low voltage trip. It just happened to trip the ground trip. Bill said that he told Mike that he should call the Shift Supervisor and let him know so they could restart the motor. Mike on the other hand told Bill that he was already on probation and was afraid of losing his job if he reported that he had slammed the door on the breaker and tripped the fan.
If there was ever a reason to call 911, it was then. All he had to do was tell them, “I accidentally tripped the PA fan when I bumped the breaker cabinet.” They would have told him to reset the flag, and they would have started the fan right back up. No questions asked… I’m sure of it. And they wouldn’t have lost their generating capacity for the remainder of the afternoon and we wouldn’t have spent 4 hours unwiring, testing and rewiring the motor in the rain with a plastic umbrella over our head.
Bill wasn’t about to tell on Mike. If Mike didn’t want to report it, Bill wasn’t going to say anything, and I understand that. I probably would have kept it to myself at the time if I was in Bill’s shoes (I’m just glad I wasn’t because I probably wouldn’t have been able to sleep soundly for the next year). But 30 years later, I might write about it in a Blog. Even though I wouldn’t have looked to Mike to teach me much about being an electrician (he was more of an Air Condition man anyway), I still loved the guy.
Mike died almost two years ago on May 29, 2011. He was from England and had lived in Canada for a time. He used to work on trains. Trains, even though they are diesel, are really electric. The Diesel engine really runs a generator that generates electricity that runs the train. I know that Mike was a good man at heart. He loved his family with all his heart. Here is a picture of the Limey:
Mike Rose. A fair plant electrician, but a great family man!
Ok. So I know what you are thinking…. There must be a story about myself in here somewhere. Well, you would be right. First of all. I always ‘fessed up to my mistakes, as my current manager at Dell knows well (yes. I still mess up after all these years). I told my current manager the other day that CLM was my middle name. (CLM means “Career Limiting Move”). So here is my power plant “mess up” story (well one of them):
In January 1986, I returned from my Honeymoon with my new wife Kelly when I found that we had hired a new electrician. Gsry Wehunt was replacing Jim Stephenson who had left the plant on February 15, 1985, which is a story all it’s own. We had just started an overhaul on Unit 1.
I remember the first Monday I spent with Gary. It was January 6, 1986 and we were working on cleaning out the exciter house on the end of the main power generator with Diana Brien (formerly Diana Lucas). We were discussing salaries and Gary was surprised to find out that I was making more than he was. Well… I had been an electrician for over 2 years and had been promoted regularly…. so I didn’t think there was anything strange about it, except that I still looked like I was only about 18 years old (even though I was 25) and Gary was about 34. I had already been promoted 4 times and my salary had gone from $7.15 to over $12 an hour.
Anyway, when that first Friday rolled around, Gary and I were assigned to Substation Inspection. Some later time I may go into the details of what “Substation Inspection” entails, but for now, let’s just stick with my “911 call.” It is enough to say that we were in the main plant substation relay house on Friday January 10, 1986 at 9:00 am. One of our jobs was to call other substations and perform a test called a “Transfer Trip and Carrier Test”. We had called Woodring Substation (Woodring is a town in Oklahoma and we had a 345 KV line going there), and I was talking to the man in the substation on the other end of the phone line.
At the same time I was showing Gary just how experienced I was at being an electrician. People had told me that you had to be a plant electrician for 5 years before you really became a “first class” electrician. Well. Here I was at 2 years, and I thought I was so good that I could do anything by now…. — Yeah… right. I told the guy on the other end of the line as I turned a switch…. Amber light… Back to Blue…. and I wrote down the value on the meter (paperwork… oh yes…. it’s that important. Like A-1 sauce).
Then I reached for the second switch. I said, “Carrier test”, then turned the switch. The lights in the relay house went out and we were in the dark. I told the guy on the other end of the line….. “Well. That’s not supposed to happen.” Then as I let go of the switch and it returned to it’s normal position, the lights turned back on. Okay……
I wrote the numbers down from the meter and said goodbye to the other faceless substation man on the other end of the line that I talked to over 100 times, but never met in person. He sounded like a nice guy. Then I headed for the gray phone. I heard the Shift Supervisor paging Leroy Godfrey (The Electrical Supervisor) on line 2 (we had 5 Gray phone lines. The Gray Phone was our PA system).
When I picked up the line I heard Leroy pick up the phone and the Shift Supervisor tell Leroy that we just lost station power in the main substation and it had switched over to Auxiliary power. I immediately jumped in and said, “Jim (for Jim Padgett, the Shift Supervisor), I did that. I was performing a Carrier test with Woodring and the moment I performed the carrier test the lights went out.” Leroy chimed in by saying, “That wouldn’t cause you to lose station power.”
Well, in my ‘inexperienced’ plant electrician way, I responded, “Well. All I know is that when I turned the switch to perform the carrier test, the lights went out, and when I let go of the switch, the lights came back on.” Leroy reiterated, “That wouldn’t cause you to lose station power.” I replied with, “I’m just saying….” and left it at that. I had done my job. They knew I was out here. They knew I had called 911 right away. I explained what I was doing…. they could take it from there.
I had hoped that I had showed Gary upfront that it doesn’t hurt to report your mistakes (even though I hadn’t made one as far as I could tell), but I was 100% sure I had done something to cause the relay house to lose power. Though, I couldn’t figure out why.
After lunch, Bill Bennett, our A foreman came down to the shop to tell me that they figured out how the substation lost station power. He said that a road grader had been grating the road down by the Otoe-Missouri reservation (which is actually called “Windmill road” I guess because there is a windmill down that road somewhere), and had hit an electric pole and knocked it over and had killed the power to the substation.
Substation Power Interrupting Road Grader
It turned out that the substation relay house was fed by a substation down that road where we have a radio tower. So, think about this. The exact time that I turned that switch in the substation, a road grater 2 1/2 miles away hits a telephone pole accidentally and knocks it to the ground and kills the power to the substation at the exact same time that I am performing a transfer-trip and Carrier test with Woodring Substation, and the time it takes to switch to auxiliary power is the exact time it took me to let go of the switch.
Don’t tell me that was by accident. I will never believe it. I think it was for the soul purpose of teaching me a useful lesson or two. First….. don’t be afraid to tell someone when you do something wrong. Second…. If you think you have control over the things that happen to you in your life… well, think again…… Third….. God watches you every moment, and if you let him, he will guide you to do the right thing when the time comes.
God bless you all.
