# l' A6 g. K0 VHi I am doing a 3 phase to ground fault analysis in pscad. Since it is symmetrical fault, the 3 phase (A, B, C) fault currents I am supposed to get should be the same. Correct me if I'm wrong please.

2 C, L7 J7 i1 LHowever the graph I got from the simulation does not show the same current for all phases (magnitude and phase). I believe that they are out of phase. Can anyone tell me why is tat? Is it something to do with the model? Thank you very much! O1 ~+ T$ b* E4 M9 ^# D# I! f( d
