Cable Fault Pre-Locator TDR Tester 12.1-Inch Touch Screen 400MHz Sampling 68km Range with Pulse Coupler | XHGG502

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. It adopts industrial-grade integrated circuits and devices with a built-in large-capacity lithium battery, which is stable, reliable and easy to use.

This cable fault tester is a special instrument for measuring and analyzing power cable status and fault distance. It combines modern electronic technology and computer technology to realize signal filtering, acquisition, data processing, graphic display and graphic analysis, completing cable speed measurement, cable length testing and 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 flashover faults.

• Industrial-grade 12.1-inch touch all-in-one computer with XP operating system for simple and convenient touch operation;
• Functions of cable wave speed measurement, cable length calibration and fault distance test;
• Fully automatic continuous sampling with timely and accurate waveform capture;
• Adopts the world's most advanced "eight pulse method" (multiple pulse method) test technology together with the shock high-voltage flashover 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;
• Ultra-high brightness large LCD screen, clearly observable in direct sunlight environments;
• The reflected signal sent by the pulse coupler is automatically displayed together with the full-length open-circuit waveform of the cable, making fault characteristic waveforms easy to identify;
• Massive test waveform storage: waveforms tested on site can be stored in order and called for observation at any time;
• Standard USB interface for convenient data export and communication;
• Built-in polymer lithium battery power supply, enabling cable open-circuit and low-resistance short-circuit testing in environments without power;
• Simple operation, high reliability and a very high cost performance.

Based on the traveling wave principle, the XHGG502 applies pulse signals to the cable under test and captures the echoes reflected at the fault point where the characteristic impedance changes, converting the reflection time into a precise fault distance. Five testing methods are integrated to cover faults from low resistance to high-resistance flashover:

This instrument provides power engineers with a reliable, comprehensive solution for power cable fault pre-location, helping minimize outage time through rapid and accurate fault distance measurement.

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.

There are three test modes of the XHGG502: low-voltage pulse, high-voltage flashover and ARC multi-shot. 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.
