    Please don't think that I was implying that the electrician didn't share in some of the blame. And, sure, there are some accident that are so strange that no one is really to blame. I just get irritated when we seem to perpetuate the divide between linemen and electricians (both sides do it). I think we would all be better off if we took some time to stand in the other's shoes and try to at least understand the other trade. I frequently work with the linemen in my area and have had almost all positive experiences; probably due in part to my participation on this forum that gives me a glimpse of the lineman trade.

    Sorry for digging up an old thread.

    One question. After the hi pot test was the secondary shorted out to a ground to remove the DC voltage?

    I believe from my own experience Clive is 100% right. The hi pot through the coils and the secondary will hold a charge after the test and must be bleeded off or an unpleasant jolt will occur. Not like 120 feels more like an electric fence. Wanna know the feelin I'm talkin about grab both leads of a meggar and let your buddy give it a crank. Lol

    In writing this post I have another question. The transformer was hi pot tested. Why was the secondary not removed before testing? Makes no sense to me. Not only will you damage the secondary conductors but you will also show bad at the can if it's a secondary issue. Me personally I would hi pot with the secondary disconnected and if that checked out I would meg the secondary.

    A DC capacitive charge could be possible. Grounding out the secondaries, we do. We have a large industrial customer. On that property we have 15 - 2500 kva and 9 other padmounts 150 kva to 1000 kva, all 277/480. My guys and I all know the electricians there and yes we ground everything before we start working anything dead. They have way too many backup generators, and backup feeds from one area to another.
