Product Introduction
The XHGG502 ARC underground cable fault locator is suitable for
measuring the low resistance, short circuit, open circuit and
disconnection faults of various materials of different
cross-sections and different media, high-frequency coaxial cables,
local telephone cables, street light cables, and buried wires.
Prevent leakage and high-resistance flashover faults. Super
powerful cable management system, automatic report generation.Main features
1. It can detect the high and low resistance faults of all cables
of 35KV and below, and it has a wide range of applications.
2. The instrument adopts the latest technology of embedded
industrial computer and the most advanced "eight pulse method" in
the world.
It got impact high-pressure flashover method and low-pressure pulse
method.
3. Any high-impedance fault presents the simplest waveform
characteristics similar to a low-voltage pulse short-circuit fault,
which is very easy to interpret.
4. With user-friendly software, full English menu and screen touch
button operation. The button definition is simple and clear. The
measurement method is simple and fast.
5. The success rate of failure detection, test accuracy and test
convenience are better than any domestic testing equipment.
6. Ultra-high brightness, large LCD screen as the display terminal,
can be clearly observed in the environment of direct sunlight
Screen waveform. The instrument has powerful data processing
capabilities and a friendly display interface.
7. With the function of handwriting board, when the waveform is
stored, the personnel, locations and fault characteristics of the
field test can be stored.
Information such as the test process is directly handwritten into
the saved document.
8. With extremely safe high-voltage protection measures. The flash
tester will not crash or be damaged in an impact high-pressure
environment.
9. Has a standard printer USB interface.
10. Simple operation and high reliability. Has a very high cost
performance.
11. No test blind zone.
12. Built-in polymer lithium battery power supply, can test cable
open circuit and low resistance short circuit fault in no power
environment.Technical dataDisplay | 12-inch industrial-grade computer control, touch operation mode; |

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.----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
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
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 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.
