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.

Pulse coupler withstand voltage 38kVDC
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).

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.
