Residual current monitoring in grounded power supplies (TT and TN systems) – VARIMETER RCM
Early detection of insulation faults, as well as preventive maintenance and servicing outside of operating hours, can prevent unexpected shutdowns of machines and systems, thus avoiding unwanted interruptions in operation, property damage and high costs. Residual current monitors of the VARIMETER RCM (Residual Current Monitor) series are available as pure AC currents and pulsating DC currents DC (type A according to IEC/TR 60755) as well as all-current sensitive residual current monitors (type B) AC currents, pulsating and smooth DC residual currents DC.
