I have an ungrounded 13.8kV Bus I would like to ground. The 13.8kV bus connects wye connected generators to a Delta - Delta step up transformer for export to the utility. When the generators are disconnected the bus becomes ungrounded. The station service transformer connects to the this 13.8kV bus. Does anyone see any inherent problems with using a Wye-Wye station service transformer (13.8/8kV - 480/277V) as the ground point? The generators are high impedance grounded.
