Abstract
Disclosed herein are systems for monitoring and protecting an electric power system using a plurality of conductor-mounted detectors (CMDs). In one embodiment, a plurality of CMDs are coupled to an electrical conductor. Each CMD may harvest power from the electrical conductor and may monitor electrical current in the conductor. When the electrical current in the conductor exceeds a fault current threshold a fault signal may be transmitted. A receiver in communication with each of the plurality of CMDs may receive the fault signal from at least one of the plurality of CMDs. A protective action may be generated and implemented to clear the fault. A portion of the electric power system affected by the fault may be determined based on identification of each of the plurality of CMDs to transmit the fault signal.
