iCP-440 Capacitor Bank Protection Relay
For Secure and Economical Bank Protection
iCP-440
Double W ye Ungrounded
Bank Application Example
Technically Advanced Capacitor Relay
■
The iCP-440 relay detects capacitor bank unbalance when the compensated neutral quality increases beyond a threshold.
It reduces outage time by pinpointing the failed components 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
B A N K
Use the iCP-440 relay 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.
