Product information "IKI-50_1F R2e"
The universal fault indicator IKI-50_1F 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_1F 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.
fault detection
- directional short-circuit detection
- directional ground short-circuit detection, directional static ground fault detection (wattmetric method), directional transient ground fault detection (wiper method), earth fault detection via pulse locating
- suitable for all neutral point treatments
- no summing transformer required
fault early detection
- fault early detection by detection of transient disturbances
- partial discharge trend detection together with CAPDIS-S2_55 (R5)
load flow measurement
- voltages, Currents, powers, frequencies, cos-phi, . ."
- Momentary and average values
- Limit monitoring
Network automation
- Extensive logic functions freely programmable with PC software KriesConfig
IKI-50_F1 R2 is maintenance-free
- No battery
- Unlimited data retention
- Fault indication in case of power failure over 6 hours
