What voltage would you normally expect to see on the secondary side of a wye/wye transformer bank where both wye points are "floated"? We had the service disconnect open and I was seeing ~900 volts on each phase to ground, and 495 phase to phase. The utility came out and connected the primary wye to their static ground and the phase to ground went down to more what I would expect on this type of system. 365, 316, 268.
