I'm trying to learn about fault analysis and I have a question about an example phasor diagram from a fault that I have been looking at. I'm pretty sure that it is a A-B phase to phase fault (high currents on lines A and B in opposite phase as well as low voltages). I've also calculated what I believe to be the fault current and fault voltage phasors by adding the respective phasor of the two lines together. Now I'm trying to determine whether the fault is close or far from where the phasor diagram was measured. Here is my thinking: Since the fault votage phasor is high and the fault current phasor is low, this would imply a high impedence suggesting that the fault exists far away from where the measurement was taken. Anyone think this is a valid assumption? Thanks for your input!
