Technically Advanced Capacitor Relay
■
The iCP-191 relay detects capacitor bank unbalance when the change in capacitor string impedance increases beyond a
threshold. It reduces outage time by pinpointing the affected phase and string. 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
■
Use the iCP-191 relay for protection and control of shunt, multi-string, fuseless capacitors 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.
