This is the neutral wire in the back of a transformer. I see no reason why a neutral wire would show hot. I talked with the plant electrician and he advised there had to be a feed back coming from somewhere. This could create a real problem if the transformer was to fail. The plant would be down for days and no telling how much that would cost in lost production.
 
He went to work on finding that source right away.
