Easergy MiCOM P64x

Transformer Protection Relays

Easergy MiCOM P64x series provides fast and complete protection for transformer faults, preserving service life. Designed for two and three winding transformers (including autotransformers), it is easy to use and the setting wizard requires only nameplate data. Models available: MiCOM P642, MiCOM P643, MiCOM P645

Easergy MiCOM P64x
  • Features

    Transformers are high capital cost assets in electrical power systems. Elimination of all electrical and mechanical stresses, although desirable to preserve transformer life, is impractical. Adaptive techniques to measure and alarm (or trip) in such instances, and advise on cumulative service duty, 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. Easergy MiCOM P642P643 and P645 Advanced Transformer Protection and Control

    The Easergy MiCOM P642, P643 and P645 address all these issues - preserving service life, and offering fast protection for transformer faults. Hosted on an advanced IED platform including IEC 61850 Edition 1 and Edition2 and PRP or HSR (parallel redundancy protocol), the Easergy MiCOM P64x incorporates differential, REF, thermal, and overfluxing protection, plus backup protection for uncleared external faults. Model variants cover two and three winding transformers (including autotransformers), with up to 5 sets of three-phase CT inputs.

    Large CT counts are common in ring bus/mesh corner applications, where the Easergy MiCOM P64x summates currents to create each total winding current, easing application of backup protection. Backup overcurrent can be directionalized, where the user includes the optional 3-phase VT input in their chosen model.

    Latest communication protocols & Ethernet redundancy
    Fully Equipped with the latest communications protocols (IEC61850 Ed1 & Ed2 available in the same device, selection by setting).
    Maximum availability and reliability of Ethernet communications thanks to the implementation of PRP/HSR standard redundancy protocols with an instantaneous recovery time (0 ms) in case of network failure.
    Dual IP address allows the device to be connected to 2 independent communication networks (e.g, SCADA system network & Maintenance network)
    Universal IRIG-B input (automatically detects modulated or unmodulated signal)

    Major enhancement to Cybersecurity
    Operational & Cybersecurity, compliant to IEC 62351, helps protect installations with security based on embedded features such as Role Based Access Control (RBAC), Port Hardening, Security Logs and Access Traceability. The IED by default includes RBAC with different users defined and a Security Administrator.

    Standard Manufacturers Warranty: 2 years
    Extended Warranty: Up to 10 years (product registration required)
