Tracing electrical conductors by high-frequency constant-energy pulse loading

摘要: Tracing, identifying and distinguishing electrical conductors in a power distribution network energized by varying or alternating voltage is achieved use of transmitter (10) which absorbs conducts pulses current the network, remotely located receiver (12) detects electromagnetic field signals corresponding to conducted through conductor. The includes means (10", 400) for time width duration each pulse relation instantaneous present on conductor during pulse, order deliver are substantially uniform constant energy content. Discrimination adjacent enhanced because strength signal remains despite nature network.
