P64 MiCOM 5th Generation
Transformer Protection Relays - P642, P643, P645
The P64, part of the MiCOM P40 Agile 5th Generation family is a transformer protection relay that helps preserve transformer service life and provides fast protection for transformer faults with a graphical HMI as standard. The platform consists of three model variants (P642, P643 and P645) that cover two and three-winding transformers (including auto-transformers), with up to five sets of 3-phase CT inputs, and offers high and low impedance restricted earth fault, and has integral asset management capability.
Key features:
- Integrated full color graphical HMI display, for single-line diagram control of the protected bay.
- Dedicated RJ45 Ethernet port for engineering access by protection engineers/operators
- High stability during external fault with heavy CT saturation due to transient bias technique
- No slow-down of differential elements due to 2nd harmonic component in fault currents
- Adaptable to transformers with considerable CT mismatch between terminals – matching factor up to 20
- Current transformer supervision operates with or without voltage inputs, fast enough to prevent any spurious tripping and alarm
- Asset health monitoring - transformer Loss of Life estimation according to IEEE model
- 10 integrated function keys, tri-color LEDs, and graphical programmable logic permit the creation of comprehensive, tailored schemes
- Simple settings - wizard requires only nameplate data
- No internal batteries in GE Vernova-branded models – removes a maintenance item and eases air-freight logistics
- Supports all major digital control system protocols, easing integration into DCS, SCADA and engineering workstations
- NERC CIP cybersecurity
- Binary inputs ESI48-4 EB2 compliant
- Harsh environment coating as standard for all GE Vernova MiCOM P40 relays protects against corrosive gases such as H2S or SO2
- Advanced Cybersecurity including AAA, Radius, RBAC, and Syslog
- Secure Data vault with 5000 events, 100 Fault records and over 1000s of Oscillography
- Advanced IEC 61850 Edition 2.1 implementation

What's New
Overview
Transformers are high capital assets in electrical power systems. Elimination of all electrical and mechanical stresses, although desirable to preserve transformer life, is impractical. Adaptive techniques to measure, alarm (or trip) and advise on cumulative service can help to schedule preventive maintenance before a costly failure occurs. Internal faults are a risk for all transformers, with short-circuits dissipating the highest localized energy. Unless cleared quickly, the possibility to rewind windings reduces and core damage may become irreparable.
GE Vernova's P642, P643 and P645 address all these issues, preserving service life and offering fast protection for transformer faults. A transient bias technique has been included, enhancing relay stability and CT requirements. Hosted on an advanced IED platform, the P64x incorporates differential, REF, thermal, and overfluxing protection, plus backup protection for uncleared external faults. Model variants cover two and three-winding transformers (including auto-transformers), with up to five sets of 3-phase CT inputs.
Key benefits:
- Backup and logging of through faults
- Simple settings – wizard requires only nameplate data
- Integrated backup overcurrent per winding or CT input - optional directionalizing when relay fitted with a 3-phase VT
- Ordering the 3-phase VT permits full monitoring and measurement of power and energy quantities
Main characteristics:
- Current loop analogue inputs [CLIO] and analogue outputs [RTD] for remote monitoring
- Optional single or dual redundant Ethernet available for IEC 61850
- Transient biasing reduces CT knee point dimensioning by typically 25% compared to historical applications
