  • HIGH-IMPEDANCE FAULT DETECTION USING WIRELESS CURRENT TRANSFORMERS
    Publication number: 20210109147
    Abstract: The present disclosure pertains to systems and methods for monitoring and protecting an electric power system. In one embodiment, a system may comprise line-mounted wireless current transformers to measure at least one parameter of an alternating current (AC), receive a synchronization signal at which to measure the AC, and send a message comprising the measured AC. The system may also comprise an intelligent electronic device (IED) to send the synchronization signal to and receive the messages from the line-mount wireless current transformers, determine whether a high-impedance fault (HiZ) exists between the line-mounted wireless current transformers, and implement a control action based on the existence of the HiZ fault.
