| Abstract: | A cable fault locator was designed to detect and analyze the faults of grounding, mixed line, to solve the problem of cable line routing and to locate the faults, which occur in all kinds of power supply bus lines in electric power, railway and various industry and mining enterprises. The general concepts of grounding faults and the basic principle of detecting faults are discussed. Moreover, the transmitting of the detecting signal and the receiving of the grounding fault signal are analyzed theoretically. The circuit diagram of the system and the program flow chart of the software are given. The designed locator could conveniently and accurately find grounding faults and mixed line faults of the equipment under test without cutting off power supply and removing or changing any cable wirings. |
