Basic function of cable fault locator In the power industry and some industries using cables, especially in some complex power systems, it is very difficult to find the fault of underground cable lines. However, the continuous emergence of versatile and easy-to-operate devices in this regard can not only reduce the high cost of detecting faults, but also reduce the unavoidable prolonged power outages when cable faults are painstakingly located (cable fault locator). Comes with a lot of convenience. 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.
Hammer (pulse) method Many electric utilities use the hammer (pulse) method. This technique is most effective in detecting high resistance faults in a simple (cable fault locator) cable system. Hammering involves the application of a pulse or surge voltage to strike a blacked out cable. When a valid high voltage pulse hits the faulted area, the fault point flashes over and produces a hammering sound audible to the operator that travels along the surface of the cable. .
But detecting cable faults often requires several hammer blows, and repeated blows can damage the cable.
