According to IEEE 665 – section 22.214.171.124 page 27, it is important for the ground conductor to run as close as possible to the phase circuit conductors; since it will cause the fault current return path reactance to be reduced.
A young electrical engineer who is recently graduated from university is in doubt about accepting that professional recommendation. He says that the reactance of cable is proportional to its inductance, and only mutual inductance is changed by cables cross distance. Also according to what he has learnt in classical electromagnetic, he knows that, cable mutual inductance increases when their cross distance is reduced. Therefore he says that standard recommendation is not correct!
Can you help to your friend for that misunderstanding?
