I was told this machine caught fire about a year ago around the transformer when the whole plant electrical system single phased. They since put in a phase balance detector that will kill the main power to the machine.
I don't see how a 3 phase transformer with a delta primary would go bad or catch fire only from single phasing. All this makes me suspicious that it has the wrong transformer.
I expect to be back at this plant this week and intend to do a little more investigating.
