ABSTRACT:
A system for monitoring at least one parameter of either an energized electrical power line conductor or at least one parameter adjacent to the power line conductor, on a real-time basis and transmitting signals indicative of the parameter to a remote location where the power line conductor itself is the transmission medium for transmitting the signals to the remote location. The transmitter is powered by either the electric or the electromagnetic field of the energized power line conductor and the transmitter receives induced energy from the conductor via a plurality of turns of wire wound around a mandrel, with the plurality of turns of wire formed as the secondary winding of a transformer, and with the mandrel being at the same electrical potential as the conductor.
