have a 277/480 3 phase panel feeding a 280 delta 208Y /120 volt transformer which then hooks to a 208/120 3phase panle.
Now across the legs I get 199-200 volts
line to ground I get 1 leg 139 volt 2leg 71 volt 3 leg 150 volt line to neutral I get 115 volts on each leg ,from neutral to ground get 50 volts .If I try to run a neutral wire in conduit it will arc any ideas on why the voltgae is off and why I have it on my neutral
any help appreciated
