PCS-915IC Centralized Busbar Relay
The PCS-915IC centralized busbar relay provides comprehensive protection solution for various arrangements of all voltage levels. The default busbar arrangements include single busbar with/without section, double busbar with/without section, double busbar with transfer bus, breaker-and-a-half arrangement and ring-breaker arrangement. The relay provides flexible configuration of the busbar topologies to meet specific applications. Due to its extensive CT input and I/O capability, the PCS-915IC is capable to protect up to 25 feeders.
It provides fast and secure low impedance busbar protection with sub-cycle tripping time. Check zone and discrimination zone of differential protection are equipped in the relay to minimize the outage zone. Advanced and patented technologies are incorporated to improve sensitivity and security, such as weighted CT saturation detection method, DPFC current differential protection.
The PCS-915IC is compatible with IEC 61850 station bus and process bus applications. It supports IEC 61850-8-1 MMS, GOOSE and IEC 61850-9-2 Sampling Value. The RJ-45 faceplate port is provided for testing and setting, allowing for easier commissioning and maintenance.
