Technically Advanced Capacitor Relay
n
With advanced features for detection and control, the iCP-640 relay helps improve reliability and reduce outage time. It detects capacitor unit failure when the compensated voltage differential or impedance change quantity increases beyond a threshold. It then reduces outage time by pinpointing the smallest affected area within the bank. Because it is easily configured to permit
the nulling of inherent bank unbalance, the relay provides maximum sensitivity for detecting internal problems.
Complete Capacitor Bank Protection
n
The iCP-640 relay is used for protection and control of shunt capacitor or filter banks. It provides backup overcurrent and
under- and overvoltage protection, voltage control, and comprehensive metering up to the 15th harmonic. Cooper
offers protective relays for a wide range of capacitor bank applications including:
voltage differential, neutral unbalance, impedance, and negative sequence.
