Breaking news-- Monday's explosion was not our fault. It also did a hell of a lot more damage than previously believed, and why it took four days for the alarms to go off is anyone's guess.
The DECO transformer is shot. The whole unit will have to be replaced. They have six or seven guys out here now, more than I've ever seen in one place, and I guess I'll be seeing them for a while. The transformer shouldn't take too long to change out-- DECO's are tiny compared with our 345-->120kV behemoths, which can be the size of a house.
The transformer actually failed on the spot that Monday when a fuse blew. The fuse wasn't discovered immediately because it didn't fall out the way a spent fuse is designed to. The house service (aka "the power in my office") didn't fail until yesterday, when it went out with no warning and screwed up my computer. Those z-phase lines to our equipment were shot, but our transformers have automatic mechanisms to protect them and DECO one didn't.
Working in the field is great.
