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.
