When calculating the fault impedance for a C-A phase fault I am taking Vca/Ica to get Zca ( I am also assuming zero fault resistance). Is that the total loop impedance or is that the one way impedance to the fault? It seems to be the loop impedance to me but from what sources I have read they...
In the Aspen Breaker Rating module there is an example for breaker and a half configurations (Section 3.3.3 in the instructions) where it states for the breakers attached to one of the buses they consider the possibility that the breaker might have to interrupt the total bus current. I don't...
