ALSTOM MiCOM P645 Transformer Protection Relays - P645916D6M00060MMiCOM
P645 Transformer Protection Relays
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 and core damage may become irreparable.
GE's P642, P643 and P645 addresses 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 over fluxing protection, plus backup protection for external unblock faults. Model variants cover two and three-winding transformers (including auto-transformers), with up to five sets of 3-phase CT inputs.
Key Features:
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 with or without voltage inputs, fast enough to prevent any spurious tripping and alarm
10 integrated function keys, tri-color LEDs, and graphical programmable logic permit the creation of comprehensive, tailored schemes
No internal batteries in GE-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 protection extends the life of the product
