Line Terminal Protection Systems

The MiCOM Agile P841 is a multifunctional line terminal IED for control and back-up protection in transmission and sub-transmission feeder bays. The P841 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.

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

 
•  Providing advanced field ground fault protection for generator applications
•  Allowing both single point and double point injection methods provides optimal application flexibility depending on system configuration
•  Reduce generator down-time by locating the fault within the field winding when connected in single point injection method
•  Designed to operate with Multilin’s industry leading G60 Generator Protection System   •  Continuously monitors and protects the generator during stopped, starting and running conditions for increased asset life
•  Reduce system configuration time by configuring the Field Ground Protection Module through the G60 Generator Protection System and the easy-to-use EnerVista Setup Software
•  Increase generator life span by easily upgrading your current G60 generator protection relay with the Field Ground Protection Module
