That's OK, Volty can hold his own with you chumps.
Then get your head out of your ass, Jake. What he described was nothing but a Corner- grounded Delta. Is this NOT what he wrote?:
"when I measure the supply source across the phases the supply I found 440 plus and minus couple volts which was some what reasonable then I measured it to ground and found surprise two legs (phases) are 440 to ground and one at ground potential: what kind system is this? Transformer is next to the unit."
It's very clear that one of the phases is solidly grounded. What's that make it Jake? Evidently you assumed that it was an open delta. Since you did not state whether it was corner grounded or center tapped, by default it was then an ungrounded open delta? Seems that you incorrectly assumed it was an open delta.....and you can't afford those kind of assumptions in your business? How about flat out errors?
Who's assuming now, Jake?
You call that great? A closed delta would be much more stable.
