Neutral over voltage in Wye grd - Wye grd transformer
Thanks for the response. We can't figure out where the zero sequence harmonic voltage are coming from. There is no corresponding harmonic current. We tried to completely isolate the generator by opening the main disconnect switch, lifted the neutral and ground cables and just energize the...- Zylar

Neutral over voltage in Wye grd - Wye grd transformer
Hi all, We have a wye grd - wye grd 12kV - 480V transformer. The utility lines are 12kV 3 wire and the neutral of the primary windings are grounded through a potential transformer (PT) at the transformer pole. The neutral of the secondary is grounded the main 480V panel. This is a generator...- Zylar
