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'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 or DNP3
  • Transient biasing reduces CT knee point dimensioning by typically 25% compared to historical applications
