Technically Advanced Capacitor Relay
■
The iCP-630 relay offers the features you need to increase system reliability and lower costs. First, the relay protects the
system by detecting capacitor bank unbalance when the compensated negative sequence increases beyond a threshold.
Then the iCP-630 relay reduces outage time by pinpointing the phase of a capacitor can failure. Eliminating the neutral
ground voltage transducer lowers installation and maintenance costs. 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-630 relay for protection and control of ungrounded 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.
