Xzh Test China Factory Arm Cable Fault Locator Underground Cable Fault Detector

The XHGG502 ARM 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 tester 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. The technical parameters meet the requirements of "GB/T 18268.1 Anti-interference Degree of Test Equipment for Industrial Sites", "DL T 849.1-2019 General Technical Conditions for Special Testers for Power Equipment Part 1: Cable Fault Flash Tester", "JJF1042-2020" Cable fault tester calibration specification" standard requirements.


 

• 12.1-inch industrial-grade computer control, touch operation mode;
• XP operating system, convenient operation mode;
• It has the functions of measuring wave speed and fault distance;
• Fully automatic continuous sampling, waveform capture is timely and accurate;
• The instrument adopts the latest technology of embedded industrial computer and the world's most advanced "eight pulse method" (multiple pulse method) test technology, and also has shock high pressure flashover method and low pressure pulse method;
• Any high-resistance fault presents the simplest waveform characteristics similar to the low-voltage pulse short-circuit fault, which is very easy to interpret.
• With user-friendly software and full English menu and on-screen touch key operation. The key definitions are simple and clear. The measurement method is simple and fast;
• The failure detection success rate, test accuracy and test convenience are better than any domestic testing equipment;

XHGG502  cable fault pre-locator


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 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.
