Research on a Kind of Wireless Sensor Relay

The goal of our system is to quickly and accurately measure current on a transmission line and relay this information wirelessly by sending a trip signal to a circuit breaker. Right now, S&C’s line of circuit switching devices does not monitor the current on a transmission line between a circuit switcher and a transformer. So the goal is to get this current measurement without making a physical connection to the transmission line and sending the current magnitude wirelessly to flag a trip signal at the circuit switcher depending on the value of the line current.
