MiCOM Agile P640 Series
Transformer Protection Relays - P642, P643, P645

Part of the MiCOM P40 platform, the Agile P64x transformer protection relays helps preserve transformer service life and provides fast protection for transformer faults. 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:

  • 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 
  • 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

What's New

MiCOM P40 Agile Explorer

Enhanced Ethernet board module with switchable Ethernet redundancy delivered in a single model.

It supports PRP, HSR and RSTP in one model, allowing a single P40 model to be used in any application requiring redundant Ethernet communications. The new module is designed to handle high density traffic in the IEC 61850-8-1 network, with time latency halved. Larger architecture digital substations can also be supported, with up to 50 nodes now possible in HSR rings.

Key Features & Benefits:

  • Universal IRIG-B – Modulated and demodulated supported in the same model
  • HSR Ring – Extended to 50 node support for larger substation architectures
  • Fast performance, particularly in onerous applications such as where process bus GOOSE is used for tripping purposes

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'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
