The working principle of the cable fault locator The cable fault locator consists of three main parts: the power cable fault tester host, the cable fault locator, and the cable path instrument. The main unit of the cable fault tester is used to measure the fault nature of the cable fault, the total length and the approximate position of the cable fault point from the test end. The cable fault locator determines the exact location of the cable fault point on the basis of the cable fault tester host determining the approximate location of the cable fault point.
For buried cables with unknown direction, a path meter is required to determine the underground direction of the cable. The basic method for testing power cable faults is to apply a high-voltage pulse to the faulty power cable to generate a breakdown at the fault point of the cable. When the fault breakdown point of the cable discharges, it generates electromagnetic waves and emits sound at the same time. Buried Cables Detecting faults in Buried Cables and Underground Residential Power Distribution (URD) systems is time-consuming and can cause inconvenient outages to users, and some techniques can damage cables.
For some equipment with high technical requirements, its operation is more complicated, and only operators who have received strict training can use it, which brings a lot of inconvenience to the popularization and application of such technical equipment. Therefore, the selection of the appropriate technology depends in part on the fault detector designer's knowledge of cable system design, and in part on the equipment and operator's knowledge of the technical expertise in this area. Having the right equipment and the expertise to work in the field is the first step to detecting faults quickly and efficiently.
