Last Tuesday was the day I stayed home because the roads iced up. Naturally, being all dedicated and everything, I had my phone by my side. So about 1400, it rings and and I’m not happy to see that it’s the tech who takes care of two of my stations deep in Cajun Country in south Louisiana. If it’s a disaster, I’m in trouble because they’ve closed the interstate and most secondary roads are impassable.
Him: I suppose you’re working from home today?”
Me: You got that right. Roads’re messed up. Please tell me you don’t have a disaster.
Him: Sort of. We keep tripping the breaker on the UPS. (Naming the station that just got a new inverter two years ago. A GOOD one.)
Me: How often?
Him: Couple of times right quick. Then it wouldn’t reset. Then it reset. Then it went all weekend. Yesterday it was doin’ it again.
Me: You need me out there TODAY?!?
Him: No. Roads’ll still be messed up tomorrow.
Me: I’ll be out there Thursday morning, around 0800. I’ll leave straight from the house.
Later he called back that there was to be a meeting at the station on Thursday morning, so I could come later. I told him I’d be out there at 0800. Sitting through the meeting wouldn’t hurt.
True to my word, I was at the station before 0800, having braved still icy roads. The meeting took place. At 1000, I headed over to the control room to look at the problem. The technician said he’d follow after he took care of a call of nature.
I walked into the control room. Noticed a couple of electric floor heaters plugged in. The building has a self-contained HVAC unit, but sometimes those things won’t keep up with the abnormally low temperatures.
I opened the door to the room where the UPS is located. It was working, humming its butt off, loaded to the max and then some. No wonder it was tripping. Since I personally installed and commissioned the thing, I knew its normal load was an amp. It’s rated for a thousand watts. At 120 volts, that’s 8.3 amps. Right now it’s pulling ten. Yeah, no wonder it’s tripping. So the question now is ‘Where’s the load coming from?”
Remember those electric heaters? 1200 watts. Ten amps. Hmmm. I wonder… I turned the nearest heater off. The meter dropped to almost zero, in other words, where it SHOULD be. Heater back on? Load’s back. And in the equipment room, there’s a receptacle that’s fed by the UPS , remains of some long-gone equipment. With the heater plugged into it.
About the time that I am having seriously deranged-sounding chuckles, the tech walks in. I pointed out the problem, laughed, told him that at least his heater would have ridden through a power failure. He changed it to another receptacle and promised to label the one from the UPS. I shook his hand and hauled off, headed back to the office.
At 1500 I’m getting ready to leave, having given sufficient effort for the day. Wrong. Phone rings. The boss.
Boss: Did I catch you at a bad time? Can you talk? (Boss is very safety-minded. If I was driving, he wants me to pull off the road to talk)
Me: Sure I can talk! I’m sitting here at my desk. What’s up? (I feel like the loser in the horror movie that’s going down into the dark basement)
Boss: The pipelines up north have lost two air compressors in a week, two separate stations. They’re identical units and it looks like the failed the same way. It may be electrical. I want you and the mechanical engineer to go up there and meet them in the morning to do a Root Cause Failure Analysis. (The nearest of the two stations is a mere four hour drive away.)
Me: You got it, boss. Lemme make a hotel reservation.
I made the reservation, walked over to the next hall, met my partner for the trip, then the two of us met with the assistant boss, looked at some pictures of the failed air compressor. Didn’t look like an electrical problem to me, but what the heck, I’m up for yet another adventure.
I got into the hotel room at 2000 hours. At 0600 I was up, and at 0630, on the road. At 0730 I was at the station. My compatriot was already there. With the station guys leading the way, we went to the air compressor building. No doubt about it, there’d been a fire. And no doubt about it, it wasn’t of electrical origin, that is, unless you point out that if it hadn’t been running on electricity, it probably wouldn’t have caught fire.
After carefully examining forensic evidence and traveling a hour to another station to look at the same model compressor to see one that hadn’t burnt to ashes, we came up with “Destroyed due to a fire of indeterminate origin, but not electrical in nature.” Somebody else can complete that investigation. I left at 1500. Got home at 1900.
And I’m tired.
