■ Product Overview

VS-2088A intelligent cable fault tester is to meet the rapid development of the IT era and the scheme of industrial power industry. It systematizes the limitations of the original cable fault tester with industrial control embedded computer platform system, network service business and USB communication technology, which greatly improves the use function, utilization value and convenient on-site environment operation of the instrument. The multi pulse cable fault tester is characterized by avoiding the defect that 90% of the complex high resistance fault waveform is difficult to read. The test software automatically identifies the card position and reads the fault distance. In particular, it provides a unique multi scheme service mode and management learning software for the increasing number of buried cable faults. The whole system meets the general technical conditions of power equipment testing instruments in the power industry standard of the people's Republic of China DL / t849.1 ~ DL / t849.3-2004, and the production follows the manufacturing measurement instrument license of the people's Republic of China shaanzhi 00000548. This set of equipment is a qualified supplier product of China Power grid and China Southern Power Grid. The system test consists of four parts: system host, multiple pulse generator, fault locator and cable Pathfinder. It is used for the test of various faults of power cable and the search of cable path and cable buried depth. As well as the accurate test of railway airport signal control cable and street lamp cable failure.
