Tesla,
it WAS a once in a lifetime event ,that's for sure.....
.. a bit more explanation, that damaged building is where ALL of the LOTO for the plant power is done,in other words , the tranformers 4160V output can be isolated in that building, but the 138Kv feeds for it are either from the generator ,or a backfeed from the utlity thru the MPT.
normally, opening the gen. breaker and the airswitch isloates the primary and a breaker in the building isolates the secondary
