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
Pre-locating cable faults with the reflectometer XHGG502 based on thelow-voltage pulse reflection method (TDR),high voltage flashover method (ie. ICE, DECAY),arc reflection pulse reflection method (ARC single shot and ARC multi-shot)
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 fault distance measured by using ARC multi-shot test mode of XHGG502.
The below picture shows cable fault distance measured by using high voltage flashover test mode of XHGG502
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.
