1. If working together with HX-4133 Cable Fault Tester, there are two locating methods:

1.1 Low voltage pulse: If only using HX-4133, open circuit and low impedance grounding faults of cable can be located, and the length of cable can be measured or wave speed of cable can be detected.

1.2 High voltage flashover: The discharging pulse voltage waveform of fault point is sampled by discharging sphere gap, which can locate fault distance.

2. Generate impulse of fixed frequency. If working together with HX-4132 Cable Fault Locator, there are following functions:

2.1 Audio frequency: locate high impedance, flash-over faults;

2.2 To pinpoint cable’s route, identify special cable;

2.3 To metallic breakdown(dead grounding), using magnetic-field measurement to locate accurately.

 It can also be used in DC HV withstand test.

HX-4133 Multi-pulse Cable Fault Tester

HX-4133 Cable Fault Locator is used to measure distance between cable faults. It’s easy to operate and with friendly interface.

It can be used alone under the low voltage pulse mode. Under the mode of pulse current,it needs to work with HX-2131 high voltage generator. Under the multiple pulse mode, HX-4133S coupler should be worked together. After distance locating, HX-4132 fault locator should be used for fault pinpointing. These products can be combined into a set of high performance and innovative cable fault testing system.



  • 7 inch LCD screen, friendly interface.
  • Multiple distance locating method:
  • Low voltage pulse method: it is suitable for the locating of the low resistance fault, short circuit fault, open circuit fault.
