Abstract Tracing and identifying electrical conductors in a power distribution network is achieved by use of a transmitter operating on a duty cycle of absorbing current pulses at a predetermined frequency from the power distribution network, and by use of a remotely located receiver which detects the electromagnetic field signals resulting from the current pulses in a predeterrmined cyclic manner of operation defined by a sample period and a reset period. During the sample period the receiver supplies an indication of the maximum received strength of the transmitter signal. The relationship of the duty cycle of the transmitter and the sampling and reset periods of the receiver reduce the potentially adverse influences of spurious signals on the receiver.
