XZH TEST portable 0-35KV and below voltage cable fault locator system cable fault detector can accurately and quickly detect the main insulation failure of power cables with voltage levels of 35KV and below; calibrate the cable length; accurately detect the direction and depth of the cable buried.
The system include a ARC multi-shot cable fault pre locator, a high voltage surge generator and a cable fault pinpointer.
Model number: XHGG502, XHHV535-2L, XHDD503D
| XHGG502 | ARC/ARM cable fault pre locator |
| XHDD503D | Cable fault pinpointer |
| XHHV535-2L | High voltage surge generator |
The system can quickly detect low-resistance, short-circuit, open-circuit and disconnection faults of various types of power cables with different cross-sections and different media, high-frequency coaxial cables, local telephone cables, street lamp cables, and buried wires, as well as high-resistance leakage and high-resistance flashover For permanent main insulation faults and outer sheath faults, calibrate the cable length.
1) Arc multi-shot Cable fault pre locator XHGG502: With industrial computer control, 12" color display touch operation mode, strong anti-interference ability;
2)System functions: fault distance measurement, fault pinpoint location, propagation speed test.
3)System test methods: low-voltage pulse,Impulse Current Method (ICE-Method = Impulse
Current Equipment), audio method, ARM - multiple pulse Arc Reflection Method (HV-supported reflection
method), acoustic-magnetic synchronization method, electromagnetic induction method, etc.;
4)TDR Test distance: >60km
5)Measurement accuracy: Rough measurement error: ±10m (absolute value) or 1% (relative value), fine measurement error: ±0.2m (fixed point, path, depth);

XHGG502 ARC Cable fault pre locator
Accurately and quickly detect the main insulation failure of power cables with voltage levels of 35KV and below; calibrate the cable length; roughly test cable fault distance
Cable fault pre-location: with the reflectometer XHGG502 based on the low-voltage impulse reflection method(TDR), and high-voltage decay(flashover) method (DECAY), arc reflection method(single-shot/ multi-shot).
There are three test mode of XHGG502, low voltage pulse, high voltage flashover, ARC multi-shot.

The below picture shows cable length or cable open circuit fault distance measured by using low voltage pulse test mode of XHGG502. When using the low voltage pulse method, it is not necessary to connect the high voltage pulse generator. Other test methods must be used in conjunction with a high-voltage pulse generator.

The XHHV535-2L high voltage pulse generator is mainly used for shock discharge during low-voltage cable fault testing. The equipment completely replaces the traditional test transformer, operation box and pulse energy storage capacitor weighing hundreds of kilograms, and integrates the energy storage capacitor, DC high voltage source, and discharge ball gap. It adopts high precision, high stability special high voltage electronic components and high-frequency technology, simple structure, ultra-light weight, and user-friendly design and operation mode, which is safe and reliable.
The XHHV535-2L High voltage pulse generator with over-current, over-voltage, over-heating automatic protection function, When working, the high-voltage pulse output is uniform and controllable. The panel is equipped with a relay, and the discharge time interval can be arbitrarily set within 0-100 seconds.
This high voltage surge generator has a super short circuit protection function, which can make the high voltage output work directly to the ground.
With 1.5 level. The voltage pointer meter shows that the impact discharge process is clearly visible. In addition, it measures the high-voltage side voltage, making the measurement accurate in real time. It has zero start protection and potentiometer zero output function. In the stop state, the voltmeter can indicate the capacitor voltage in real time, which is convenient for users to check and discharge after operation.
We are a professional manufacturer of cable fault detection equipment, we can customize the technical solution for you.
