Why does the voltage drop or become extremely low at the location of a fault during a fault?
Is it because the high magnitude of the fault current causes a large voltae drop across the rest of the system upstream, or is it because the fault weather its a L-L or L-G no longer has a voltage difference/reference between another line or ground depending on the type of fault?
