Method for locating fault of cables, e.g. middle or high voltage cable, involves arranging distant units with sensors for signal for detecting impulse electrical field as electromagnetic signal

摘要

The method involves arranging distant units (4) with sensors (5,6) for a signal for detecting impulse electrical field as electromagnetic signal and for another signal for receiving of the acoustic occurrence as acoustic signal. The signals are fed for fault distance calculation of an integrated evaluation unit provided as a computing unit in the form of a microcontroller (12). Global system for mobile communicationsmodules are utilized as transmitter.
