Easergy MiCOM P44x

High Performance Relay Distance Protection

Easergy MiCOM P44x provides high speed and high performance distance protection for all overhead lines and cable applications and offers a comprehensive range of protection functions as standard. Models available: MiCOM P441, MiCOM P442, MiCOM P443, MiCOM P444, MiCOM P445, MiCOM P446

Easergy MiCOM P44x
  • Features

    Easergy MiCOM P44x is complemented by various serial and Ethernet communication protocols including IEC 61850 and a multi-language HMI featuring English, French, German, Spanish, Russian and Chinese. Protection is further enhanced by the use of Programmable Scheme Logic within the device.

    The range offers quadrilateral (polygon) or mho characteristics with a long history of high performance, load blinding areas, comprehensive range of teleprotection schemes, Power swing alarm and blocking and Multishot autoreclosure with check synchronism. Easergy MiCOM P44x series with Process Bus and PTP1588 offers a solution compliant to latest standards of  IEC 61869 and IEC 61850 9-2 LE including PRP redundancy and cyber security.

    Housed in 40TE, 60TE or 80TE, 4U case sizes, this advanced distance protection range has fault clearance times of 0.7 to 1 cycle depending on model.  Easergy MiCOM P441, P442 and P444 operate on Quadrilateral distance characteristics, whereas Easergy MiCOM P443, P445 and P446 offer both Quadrilateral and Mho distance characteristics.

    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 Manufacturer’s Warranty: 2 years 
    Extended Warranty: Up to 10 years (product registration required, applies to Easergy MiCOM, please check with your local representative for availability, some exclusions apply).
