MiCOM P64x

Advanced Protection Relays for Complete Protection and Control of Transformers

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 P641, MiCOM P642, MiCOM P643, MiCOM P645

  • Tính năng

    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. MiCOM P642, MiCOM P643 and MiCOM P645 Advanced Transformer Protection and Control

    The 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 and PRP (parallel redundancy protocol), the 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 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.

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