Capacitor Bank Protection

As you would expect from the leading supplier of high voltage capacitors, Cooper offers an unexcelled range of capacitor bank protection relays : iCP-191 Fuseless, iCP-440, iCP-630 and iCP-640.

Edison Idea iCP-191 Impedance-Based Fuseless Capacitor Bank Control and Monitoring System

The iCP-191 is a member of Cooper Power Systems’ Edison Idea line of protective relays. The iCP-191 is a full-featured relay suitable for multi-string, fuseless, grounded shunt capacitor bank protection applications. The relay calculates the apparent impedance of each string and determines capacitor unit failure when the impedance changes beyond a threshold. Protection on a per-string basis permits enhanced sensitivity and rapid identification of capacitor problems to the effected string.. The iCP-191 also provides advanced power quality, metering, communication and PLC functions.

Edison Idea iCP-440 for the Neutral Unbalance Protection of Grounded and Ungrounded Capacitor Banks

The iCP-440 is a member of Cooper Power Systems’ Edison Idea line of protective relays. The iCP-440 is a full-featured relay suitable for shunt capacitor bank protection applications. The relay is ideally suited for new or retrofit applications of fuseless or internal/externally fused banks requiring neutral unbalance protection. It utilizes voltage or current neutral unbalance to provide protection for both grounded and ungrounded banks.  Single or split-wye bank configurations may be accommodated.  The relay easily permits nulling of inherent bank unbalance and compensates for real time system unbalances (single-wye) for maximum sensitivity. The iCP-440 also provides advanced power quality, metering, communication, and PLC functions.

Edison Idea iCP-630 for the Protection of Ungrounded Shunt Capacitor Banks

The iCP-630 is a member of Cooper Power Systems’ Edison Idea line of protective relays. The iCP-630 is a full-featured relay suitable for ungrounded shunt capacitor bank protection applications for both externally fused and fuseless capacitor banks. Reduce bank procurement, installation and maintenance costs by eliminating the need for the voltage transformer connected from the neutral to ground. Single or split-wye bank configurations are accommodated. The relay easily permits nulling of inherent bank unbalance and compensates for system unbalance thus permitting maximum sensitivity. The iCP-630 also provides advanced power quality, metering, communication and PLC functions.

Edison Idea iCP-640 Voltage Differential and Impedance Unbalance Capacitor Bank Control and Monitoring System

The iCP-640 is a member of Cooper Power Systems’ Edison Idea line of protective relays. The iCP-640 is a full-featured relay suitable for fuseless, internal or externally fused shunt capacitor or filter bank protection applications. The relay is ideally suited for new or retrofit applications where highly sensitive capacitor unbalance detection based on voltage differential and/or impedance is required. The relay easily permits nulling of inherent bank unbalance thus permitting maximum sensitivity to detection of internal problems. The iCP-640 also provides advanced power quality, metering, communication and PLC. functions.
