Wasn't my work.
The customer had a failure on the primary side... I just opened the xfmr and cleaned out all the dirt and cobwebs, checked connections, etc...
The date on the fuses in the MV switch feeding the primary side of the xfmr was February of '89. The switch itself said November '88 on the tag.
Neither the switch or the xfmr looked like they had been cleaned/PM'ed in 35 years. In fact, the chain on the throw handle of the switch was rusted and broken. We had to call the utility to pull the cutouts because we couldn't shut it off.
You can't see it in the picture but there was oil leaking out around the X2 and X3 bushings on the secondary, and around the H3 bushing on the primary.
There was a whole list of shit wrong. We cobbled it back together to get them up and going and sent a list to the boss. He's going to break it down line item style and give them a quote to get everything back to ship shape.

Primary side pic to satisfy the rules. It's just a "temporary" band-aid to keep the lights burning and motors turning... We'll see if they actually follow through or let it go until the damn thing burns down.
