The XHGG502 tdr underground cable fault locator adopts an
industrial-grade 12.1-inch touch all-in-one computer and a simple
operating software interface to realize human-computer interaction
testing. Adopt industrial-grade integrated circuits and devices,
built-in large-capacity lithium-ion battery, stable and reliable,
and easy to use.
This cable fault tester is a special instrument for measuring and
analyzing power cable status and fault distance. This cable fault
tester adopts the combination of modern electronic technology and
computer technology to realize signal filtering, acquisition, data
processing, graphic display, graphic analysis, to complete Cable
speed measurement, cable length testing, cable fault distance
testing.
This cable fault locator is suitable for low-resistance,
short-circuit, open-circuit and disconnection faults of power
cables, high-frequency coaxial cables, street light cables, and
buried wires of various materials with different sections and
different media, as well as high-resistance leakage and
high-resistance flashing. network failure.

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.
