Individual Digital Grounding Indicator SЗИЦ-D(M)-1 for Electrical Network Isolation Monitoring

SZIC is designed to assess the insulation level with the help of a digital indicator and to monitor the critical insulation resistance of an electrical network fed from a single power source. SZIC is designed for use in existing and newly built automation and communication devices. In it with the help of jumpers the adjustment to different voltages and current character of the controlled power supply source of load circuits is provided. The scheme excludes false triggering of the NWIC and resetting of the triggering memory when switching the power feeders and starting the DGA.
