35KV cable fault locator

35KV cable fault locatorSystem composition

The cable fault tester consists of a host, a path signal generator, a path signal receiver, and a positioning instrument, which can complete two tasks: cable fault testing and cable data management.

The host performs measurement control, data processing, and cable data management.

The fault tester can be used in conjunction with the host to measure the distance between the fault point and the testing end at one end of the faulty cable, as well as to measure the length of the cable and the propagation speed of radio waves in the cable.

The path signal generator can generate intermittent sine wave signals with a maximum amplitude of 30V and a frequency of 15KHZ, which are used to locate cable paths.

The path signal receiver is used to receive path signals, search for cable routing, and estimate cable burial depth.

The locator is used for precise positioning of fault points.
