The GE MiCOM P841 Relay is a multifunctional line terminal IED for control and back-up protection in transmission and sub-transmission feeder bays. The GE MiCOM P841 Relay provides management of single or dual breaker autoreclose logic schemes with synchrocheck.

Key features:

• Extremely versatile, e.g. managing leader-follower reclosing schemes in the event of dual breaker application
• Transmission-class circuit breaker failure protection
• Operator control and plant status indication facilities – 10 fully programmable function keys and tri-color LEDs

Models:

• P841A Line Terminal Management IED
• P841B Used for line terminals supplied by two circuit breakers, such as mesh/ring bus, double-bus, and breaker and a half feeding

What’s New

Enhanced Ethernet board module with switchable Ethernet redundancy delivered in a single model.

The new board module is supported on P841 SW 76, 79 and 86.

It supports PRP, HSR and RSTP in one model, allowing a single P40 model to be used in any application requiring redundant Ethernet communications. The new module is designed to handle high density traffic in the IEC 61850-8-1 network, with time latency halved. Larger architecture digital substations can also be supported, with up to 50 nodes now possible in HSR rings.

GE MiCOM P841 Relay Key Features & Benefits:

• Universal IRIG-B – Modulated and demodulated supported in the same model
• HSR Ring – Extended to 50 node support for larger substation architectures
• Fast performance, particularly in onerous applications such as where process bus GOOSE is used for tripping purposes
