PCS-9611S Feeder Relay

PCS-9611S is a protection, control and monitoring unit for various primary equipments (such as overhead line, underground cable, capacitor and transformer etc.) on solidly grounded, impedance grounded, Peterson coil grounded and ungrounded system. With its flexibility and the powerful PCS-Studio configuration tool, the PCS-9611S offers future-oriented system solutions with high investment security and low operating costs.

The PCS-9611S is widely adopted not only for conventional substations, but also for digital substations. It supports IEC 61850 Editions 1 and 2 and provides GOOSE and SV network interfaces with high real-time performance. The process level network supports peer-to-peer (P2P) mode and networking mode, including single network mode and dual network mode. The station level network can also receive and send MMS messages (such as interlocking signals) or process level GOOSE messages (such as circuit breakers or disconnectors positions and trip signals).
