Huazheng Electric HZ-501B Underground Cable Fault Location System

I. Overview

 The cable fault tester, has simple operating software interface, adopts industrial integrated circuit and device, also has built-in large capacity lithium-ion battery, stable, reliable, and easy to use.

The cable fault tester is a special instrument for measuring and analyzing the power cable fault state and fault distance. The cable fault tester adopts modern electronic technology to realize signal filtering, acquisition, data processing, graphic display and graphic analysis to complete cable speed measurement, cable length test, cable fault distance test and resistance measurement.

The cable fault tester is suitable for low resistance, short circuit, open circuit and break fault, leakage high resistance and flashover high resistance fault of power cable, coaxial cable, street lamp cable and buried wire of various materials with different sections and different media. The technical parameters meet the standard requirements of "DL/T 849.1 General Technical Conditions for special tester for power equipment Part 1: Cable Fault flash Tester" and "JJF1042 Calibration Specification for Cable Fault Tester".
