The AC/DC sensitive CTBS25 (type B) measuring current transformers convert system leakage and fault currents into an evaluable measurement signal. The devices are suitable for detecting fault currents with smooth DC components. The measuring current transformers can be used in DC, AC, and 3(N)AC systems. The measurement signal is evaluated using devices of the RCMS460/490 or EDS440 series, to which the measuring current transformers are connected.
