Portable cable test and fault location system on low and medium voltage power cables


Product features

HM-300 full intelligent multi-pulse cable fault tester is catering to the rapid development of industrial-grade power industry solutions and IT era, using the industrial control embedded computer platform system, network service business, USB communication technology for the limitations of the original cable fault tester. Systematization greatly improves the use and utilization of the instrument and the convenient on-site environment operation. The biggest feature of the multi-pulse cable fault tester is to avoid the defects that 90% of the complex high-resistance fault waveform is difficult to read. The test software automatically recognizes the card bit to read the fault distance, especially for the increasing number of buried cable faults. Unique multi-program service and management learning software. The whole system meets the general technical conditions of the power equipment special test equipment of the People's Republic of China power industry standard "DL/T849.1 ~ DL/T849.3-2004", and the production follows the license of the manufacturing instrument of the People's Republic of China, Shaanxi 00000548, the set The equipment is a qualified supplier of the State Grid and China Southern Power Grid. The system test consists of four parts: system host, multiple pulse generator, fault locator and cable path instrument. It is used for testing various faults of power cables, cable path and cable burial depth. And accurate testing of railway airport signal control cables and streetlight cable faults.
