Product information "IKI-50_2F R2e 1%"

The universal fault indicator IKI-50 R2e is the appropriate solution for intelligent distribution substations and offers distribution system operators a high level of transparency and cost-effectiveness. The IKI-50 R2e includes all algorithms for selective fault detection. It is suitable for all neutral point treatments. Information on faults, load curves or limit violations is thus available on site as well as in the central network control center. Faults can be detected and localized immediately.

The IKI-50_2F R2e 1% monitors two feeders. Its two inputs for voltage measurement are designed for ohmic sensors and allow precise measurement with a maximum measurement deviation of 1%.
