Product Description

XHHV535-2L+XHGG502A+XHDD503C  Portable Cable Fault Location system
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 portable cable fault location system is a 1-phase mobile cable test and fault location system made in a form trolley. It is designed for

• Testing medium-voltage cables with direct current voltage Up to 32kV

 

• Pre-locating cable faults with the reflectometer XHGG502A based on the

low-voltage pulse reflection method (TDR),
high voltage flashover method (i e .DECAY, ICE),
arc reflection pulse reflection method (ARC single shot and ARC multi-shot) 

• Pinpointing cable faults with the AMS method with 1024 surge generator and suitable signal receiver.
