XZH TEST portable cable fault locator set is designed for 35kV and below underground cable fault location.
Consist with a cable fault pre-locator(XHGG502), a cable fault pinpointer(XHDD503D), a max impact voltage 35kV high voltage surge generator(XHHV535-2L)
★Cable fault pre-location: with the reflectometer XHGG502 based on the low-voltage impulse reflection method(TDR), ICE(impulse current test method), multiple impulse(ARC-multi-short)arc reflection method.
★Cable fault pinpoint location: XHDD503D uses acoustic-magnetic synchronization method, digital display waveforms of sound and magnetic, judge cable fault point by time difference and earphone, make detection more easier.
The portable cable fault location system is configured with the removable ARC cable fault locator with ultra-high brightness, large LCD screen 12.1" display with touch control, making the process of fault pre-location quick, easy and efficient.
High voltage 1225 J surge generator is accompanied by a surge levels switch which allows to achieve the maximum surge impulse energy at 35 kV.
It has features operator safety assurance systems and provides a reliable and comprehensive technical solution for low- and medium-voltage cables faults.

503D has a powerful background noise reduction function, especially suitable for complex environment cable fault accurate fixed point, acoustic magnetic synchronous detection, acoustic and magnetic wave time difference directly displayed on the screen, making fault judgment more simple.
503D also has auxiliary path detection function, when the fault point, the screen shows the probe on the left or right side of the cable, so that the operator does not deviate from the cable path.
Portable waterproof carrying case with no less than IP54 protection grade.

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.
