I'm calculating the 3 phase and ground fault current on a 23kV corner-grounded delta system in Aspen. I have not been able to determine how to model such a transformer in Aspen; it is currently modeled as an ungrounded delta.
My thinking is that the line-line fault current on an ungrounded delta would be equivalent to a line-ground fault current on a corner grounded delta. Can anyone weigh in? Or provide guidance on how to calculate such a fault current?
