Refurbishment Solutions – “If It’s Blue Think to Renew”

GE Vernova’s latest MiCOM P14 MiCOM 5th Generation series models P141 to P145 inclusive offer an ideal path to refurbish an older installed base of MiCOM P140 relays. Whether those older products were initially sold as GE or AREVA-branded products, newer models retain pin-pin refurbishment capability. Advantageously, users can benefit from the advancements made in protection, control, communications, hardware and cybersecurity that have taken place in the intervening years. The new P40 retains form, fit and function compatibility but delivers the latest platform and software ready for today’s environment, and for future-proofed application for the decades ahead.

Pin-Pin Upgrade Methodology:
  • Take the order code (CORTEC) of the older relay being removed, typically a blue case relay
  • Translate to today’s latest GE Vernova MiCOM model, adding Ethernet options if required
  • Order the new P40 relay
  • Extract settings and logic, use S1 Agile toolsuite to convert settings
  • Detach the terminal blocks from old relay, leaving wiring attached / detach terminal blocks from the new.
  • Carefully examine the terminal blocks to see that no physical damage has occurred since installation
  • Mount new relay. Old relay blocks fit straight onto the new relay - safer, less wiring to reconnect.
  • It is recommended to apply rated current and voltage to the relay CT/VT inputs during secondary injection testing to check the continuity of the CT/VT terminal block connections to the relay.
  • Download converted files
  • Test, return circuit to service with only minutes of downtime
