III. Applications:

 

Cable Fault Distance Locator is widely used for the test of various types of power cable fault, cable path, cable buried depth, as well as railway, airport control signal and cable failure precision test.

The Cable Fault Distance Locator has three modes of operation as below:

Low voltage pulse:can be used to measure the distance of cable fault, low resistance and short circuits.

Pulse current : in combination with the high-voltage signal generator, can be used to measure the distance of the high resistance and the flashover fault. The

Multiple pulse:multi-pulse ranging method can be used to measure the distance of high-resistance and flashover faults of power cables under the cooperation of the high-voltage signal generator and the multi-pulse generator.
