Detection of voltage condition in high voltage equipment according to IEC61243-5. Integrated continuous three phase voltage indication. No battery required For voltage detecting and self test no external power supply or battery is required. Completely free of maintenance The device performs a permanent online insulation measuring. Complete isolation monitoring of capacitive divider. Isolation monitoring of primary and sekundary part of capacitive divider and indication in case of a isolation problem. Adjustable divider Secondary party of capacitive divider is adjustable by user in 6 steps. Therefor Capdis is easily adjusable to different voltages and different primary parts C1 of capacitive dividers. Interface for Smart-Grid Systems Voltage interface for Smart-Grid Systems with voltage measurement and fault detection ( IKI-20a, IKI-50) . Inherent safety The CAPDIS-S2+ includes a self test which offers inherent safety, no external test device is required. Optional broken signal lead detection. Relay outputs For remote monitoring of voltage condition two relay contacts are integrated. The relays are driven by auxiliary voltage. Integrated 3-phase test point Acc. to the LR-specification in IEC 61243-5. The test point can be used for phase comparison and phase sequence test. Integrated U0-interface For easy intallation of earth-fault direction relay IKI-EDI-W or partial discharge monitoring.
