for  Capacitor Bank Protection and Control in One Relay from SEL

The SEL-487V Capacitor Protection and Control System combines synchrophasor technology and flexible communications with complete capacitor bank protection and control in one economical relay.

The SEL-487V protects and controls grounded and ungrounded, single- and double-wye capacitor banks. The settings assistant, based on the IEEE C37.99 standard, automatically performs calculations for application-based settings. Faulted phase and section identification logic quickly locates faulty capacitor units, reducing repair time and cost. Synchrophasor technology improves situational awareness and provides real-time control.
