MAIN FEATURES

General Features

The CPR 500 provides comprehensive protection for the capacitive, inductive and resistive elements of three-phase medium and high voltage shunt capacitor banks and harmonic filter circuits.

Design Features

The CPR 500 has a touch user interface and fulfills the IEC61850 server requirements. It is compatible with communication expansion modules IEC61850 with RS485 and Ethernet, TCP/IP, with RS485.

System Protection

The CPR 500 limits the possible damage to capacitors in a power factor correction system. The main objective is to remove the protected equipment from service before damage occurs.

Protection Function

For repetitive overvoltage protection up to the 50th harmonic, overcurrent, undercurrent, and earth fault protection. Protects capacitors, inductors, and resistors against overheating.

PRODUCT APPLICATIONS

Capacitor Protection Relay CPR500

Reliable protection of capacitor
and harmonic filter circuits.

Capacitor and filter banks need to be protected against disturbances to prevent unscheduled outages. The CPR 500 provides extensive features to ensure trouble free operation.
