M402

Electronic Current Burden

Electronic Current Burden M402 is used as a load in the secondary circuits of Current Transformers during their verification and calibration

With the wide programmable burden power range provided, most national and international standard burdens or specific customer values can be set

 

    FEATURES AND BENEFITS

    • Wide range of burden values according to standards: IEC 61869-2, IEC 60044-1, IEEE C57.13, VDE 0414-1, GOST 23624, GOST 7746
    • Standard and non-standard burden power values at rated secondary currents: 1; 2; 5 А
    • Rated burden power range:

    0; 0,5…100 V·А, cosφ = 0,5…1 at 50 and 60 Hz

    • Cable, contact and internal test set (Comparator) resistances are compensated by four-conductor connection
    • Simple use by intuitive user interface
    • Storage of individual burden settings, which can be retrieved as required
    • Possibility of using with automated CT calibration systems
    • The burden values range can be extented by connecting several devices in series
    • Small size and low weight
