ABSTRACT:
The faulted cable is connected in a loop with a spark gap at one end. Voltage is applied until the spark gap breaks down and the arrival time of the resultant forward wave is measured at both ends of the loop to measure total cable length. Next, the spark gap is opened and the voltage is built up until the fault breaks down. The time of receipt of the wavefront at the two ends of the loop is measured to determine the location of the fault. The apparatus comprises the power supply equipment, the spark gap and the time measuring equipment with its voltage divider and clamp.
