Isolation Control System Terminal EKRA-SKI for Automatic Monitoring of DC Insulation

The terminal of the insulation monitoring system EKRA-SKI is designed to fulfil the following functions:
- automatic control of the equivalent insulation resistance of the DC network as a whole with respect to "ground"
- determination of insulation resistance of each pole of the network relative to "ground"
- determination of connections with damaged insulation without disconnecting consumers from the network
- determination of the polarity of the damaged network pole
- operation without current injection into the controlled network to avoid false triggering of RPA and PA devices
