So I'm in a disconnect today and check voltage to ground (no neutral in system)
The voltages were..
A phase to ground 500 V
B phase to ground 0 V
C phase to ground 500 V
Phase to phase was all 500 V.
I work for a municipality, so the first thing I do is call the inspector over and tell him I think we need to get a lineman out here. He checks voltage and says "its a wild leg" then walks off. I assume he was talking about a center tappdd delta system, but it doesn't make any sense to me because its not a 240 V system and it doesn't have a high leg, it has a dead leg and supper high voltages on the others.
Anyone know what's goin on? I'm lost here and we have about 1 million dollars in AC equipment running off this system. Seems to me something is bad wrong, but all my experience is with Wye systems.
