Product Description


Cable fault locator system is composed of power cable fault pre-locator,integration high voltage power supply, path locating meter ,cable pinpointing meter and multiple impulse generator.
It 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.


  1. 12.1-inch resistive touch screen, touch pen touch mouse dual control
  2. Max test distance could be up to 100Km.
  3. Using three kinds of test method|: TDR, ARC and HV pulse
  4. The HV generator, integrated design, built-in capacitor, simple wiring.
