Universal protection for power systems

Abstract

A system includes a transmission cable with a first main conductor wire. A sense wire is wrapped around the first main conductor wire with a sense resistor in series electrically with the sense wire. The transmission cable includes one or more additional main conductor wires each including a respective conductor. A protection system is operatively connected to the transmission cable, including a leakage current sensor circuit (LCSC) operatively connected to the sense wire to provide feedback indicative of current in the sense wire. A controller is operatively connected to provide feedback based control to a plurality of switching devices for fault protection. The controller is operatively connected to receive the feedback indicative of current in the sense wire from the LCSC for feedback based control of the plurality of switching devices.
