HighPROTEC Transformer Differential Protection

    HighPROTEC Transformer Differential Protection

    The MCDTV4 offers an all-in-one solution for HV, MV and LV transformers and it offers much more than just a differential protection package. Furthermore it can detect critical operation states based on voltage measurement (e.g. Overexcitation). The MCDTV4 provides in addition to that an Interconnection package. This can be used for mains protection at the point of  common coupling (e.g. for directional reactive power undervoltage protection). The integrated backup protection package enables the MCDTV4 to act as backup protection (e.g. for downstream breakers). Additional features like demand management are available without extra charge.
