+ ?8 K7 Q+ g2 q* O% H HHi 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. ; Y) D2 a `3 R& d; g7 \; K 6 r* W+ a* i7 f3 JHowever 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 : j9 C9 Y+ \3 e2 L: J' k; E+ W " n. ?" s$ Z& \# m% |$ a7 FPS.
