Abstract: The present disclosure relates to powering distributed sensors used to monitor electrical and/or environmental conditions and to powering other equipment associated with electric power systems. In one embodiment, a system may be used to mount a sensor in proximity to a reference conductor. An electric field power conversion subsystem may generate a usable electric potential from an electric field created by the electric power system and existing between the reference conductor and another conductor (e.g., another phase conductor, a ground conductor). The sensor powered by the usable electric potential may provide a measurement of a condition associated with the electric power system. A communication subsystem powered by the usable electric potential may communicate the measurement of the condition to a monitoring system.
