Murray loop test employs the principle of wheatstone bridge for locating the fault. To perform this test, it is necessary to have a sound cable running alongside the faulty cable. One end of the faulted cable is connected through a pair of resistors to the voltage source. Also a null detector is connected. The other end of the cable is shorted.
Underground cable locations are not always obvious, which can lead to unwary diggers damaging cables or being electrocuted. Operations are more difficult since underground cables' high reactive power produces large charging currents, making voltage control more difficult. Large charging currents arise due to the higher capacitance from ...
