The reflected signal sent by the pulse coupler is automatically
displayed, and the full-length waveform of the open circuit of the
cable is displayed at the same time. This makes the representation
of the fault characteristic waveform extremely simple. There is
only one type of high-resistance fault waveform, that is, the
short-circuit fault waveform similar to the low-voltage pulse
method.
The fault distance is automatically displayed and there is no test blind zone.
With the function of storing massive test waveforms: The waveforms tested on site can be conveniently stored in the instrument in a prescribed order for recall and observation at any time.
The measured fault point waveform and the good-phase full-length open-circuit waveform can be displayed on the screen at the same time for comparison on the same screen and superimposed comparison. Makes the judgment of the fault distance more accurate.
Built-in polymer lithium battery power supply: it can work continuously for more than 4 hours after being fully charged. Fully meet the requirements of on-site testing. It can also work with an external AC power supply.
Eight pulse transmission and fault reflection signals are automatically displayed, and the full-length waveform of the cable open circuit is displayed at the same time. This makes the representation of the fault characteristic waveform extremely simple. There is only one type of high-resistance fault waveform, that is, the short-circuit fault waveform similar to the low-voltage pulse method. The fault distance is automatically displayed and there is no test blind zone.
Working conditions: temperature -25ºC~+55ºC, relative humidity 85%, atmospheric pressure 750±30mmHg.
high voltage flashover method (ie. ICE,DECAY),
arc reflection pulse reflection method (ARC single shot and 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.
