Smart Portable Light Weight 5.7" With Printer Medium Low Voltage
Underground TDR Cable Fault Locator
XHGG501B is designed for underground power cable fault
per-locating, to provide quick accurate and safe measurement
solution. Measure the power cable of different sections, different
media of various materials, short circuit, open circuit short line
fault and the low and middle resistance fault.
Great for KV substation, civil power supply system and power energy
sources applications.

battery, charging process, the instrument screen light.
Press the switch button to the "O" bit to shut down;
English version available
There are two test methods: low voltage pulse(LV TDR), high voltage
flashover(ICE)
The following picture shows the high voltage flashover method for
testing cable fault distance.

The TDR can be used in conjunction with various high-voltage
equipment to perform a rough measurement of the fault distance of a
high-resistance cable.
