3 Phase 240 480 wye delta floated high side
Question on a 3 phase overhead bank,Transformers are wye 7970 floated high side.On secondary side its wired delta,voltages are 280 280 and 265 phase to ground.480 phase to phase on all other checks,why 265 volts on the one leg to ground but like I said 480 phase to phase with any other leg?No neutral on low side...
