A short circuit fault is located by varley loop test. The ratio arms are set at P=5 ohms and Q=10 ohms and the values of variable resistance S are 16 ohm for position 1 of switch K and 7 ohms for position 2.The sound and the faulty cables are identical and have a resistance of 0.4 ohms/Km. Determine the length of each cable and the distance of fault from the test end.
