4A fault is located somewhere on a 78 m line. Use the Varley loop test circuit as shown in the following figure with R1=100 Da R=100 2. In position 1, R4 at balance was 36.5 2. In position 2, R4 was found to be 20.4Q. Determine the distance, dx of the fault from the test set. Da Ra R1 Лuтрer Wire Vs + (V) Rx R4 Fault to R3 ground
