Residual Current Monitors (RCMs) are used for monitoring of the residual currents in electrical power systems without the need for fast system shutdown. The RCM of Type B/B+ can measure DC and AC residual currents at frequencies of up to 100kHz, which makes it compatible to multitude of industrial applications, loads and generation sources. With its user selectable settings, this RCM offers flexible platform for residual current measurement which fits every possible usage both at the moment the industrial plant is designed, but also in case of extensions with new modern loads operating with DC voltages or at high switching frequencies which increase the amount of leakage current in the system.
