Abstract
The present disclosure pertains to systems and methods for measuring electrical parameters in an electric power system. In one embodiment, a system may include a line-mounted wireless current sensor comprising a current monitoring subsystem to generate a current measurement of an alternating current flow through an electrical conductor. The line-mounted wireless current sensor may harvest power from the electrical conductor. A processing subsystem may generate a message comprising the current measurement, and the message may be transmitted at a synchronization point using a wireless communication subsystem. An intelligent electronic device (IED) may receive the message. The IED may further generate a voltage and generate a phasor based on the current measurement and the voltage measurement. A control action subsystem may implement a control action (e.g., selectively connecting or disconnecting a capacitor bank) based on the phasor.
