The highly sensitive CTAC series measuring current transformers in combination with RCM or RCMS series residual current monitors and evaluators convert AC currents into an evaluable measurement signal.

They are also suitable for use in insulation fault location systems for IT systems (EDS). The current transformers measure the locating current generated by a PGH locating current injector or an ISOMETER® iso685. In combination with EDS series insulation fault locators, the locating current is converted into an evaluable measurement signal.

The connection to the respective devices is made via a two-wire cable.
