GE VERNOVA | MULTI-FUNCTIONAL LINE TERMINAL PROTECTION SYSTEM | MICOM P84

The P84, part of the MiCOM P40 Agile 5th Generation family, is a multi-functional line terminal Protection that delivers high performance processing and a graphical HMI as standard. It is ideal for HV, EHV and UHV applications on lines and cables for 1 or 2 breaker applications with patented adaptive auto-reclose functionality.

Applications

  • Single circuit breaker applications
  • Breaker and a half, or mesh feeding with two sets of CT inputs, with settable independent CT ratios
  • All applications where feeder main or backup overcurrent protection is required - suitable for solidly earthed, impedance earthed, Petersen coil earthed and isolated systems

Key Benefits

  • Full suite of monitoring, control and recording capabilities plus fault locator.
  • Multi-shot auto-reclosure with check synchronism - adaptive technology to detect fault arc extinction and accelerate the dead time or drive to lockout for persistent faults
  • Transmission-class circuit breaker failure protection (< 3/4 of a cycle)
  • Harsh environment coating as standard for all GE Vernova's MiCOM P40 relays protects against corrosive gases such as H2S or SO2
  • No internal batteries in GE Vernova-branded models – removes a maintenance item and eases airfreight logistics
  • Advanced Cybersecurity including AAA, Radius, RBAC, and Syslog
  • IEC 61850 9-2LE Process Bus capability with PRP in all models
  • Secure Data vault with 5000 events, 100 Fault records and over 1000s of Oscillography
  • Binary inputs ESI48-4 EB2 compliant
  • Advanced IEC 61850 Edition 2.1 implementation
  • Dedicated RJ45 Ethernet port for engineering access by protection engineers/operators
