We tested a small, 3-phase, dry type, 20kVA transformer that is delta to wye and 1000V/416/240V. We took a multimeter and measured from from Phase A to ground and phase B to ground on the low side and measured 416V. When we measured from phase C to ground we measured 0V. This told me that phase C and ground were at the same potential. If the transformer was energized shouldn't it have been damaged if this was occuring? I'm wondering if anybody else has ever observed something like this before.
I only ask because someone wants to hook this XFMR up to a small distribution panel. There are no 3 phase loads in the distribution panel but I'm almost positive that something will get damaged if we do.
