Product information "IKI-55"
The IKI-55 Feeder Control Unit can be used in load switchgear for directional fault detection, load flow measurement, and control of load and ground switches. Likewise, a number of automation and monitoring functions are available with the IKI-55.
The IKI-55 is network-capable in its basic version and can communicate with the control station and other remote stations via various communication protocols. It can also be used as a Modbus master. The IKI-55 M is a Modbus-only variant.
The IKI-55 is designed for the connection of small-signal current transformers according to IEC 61869-10 as well as small-signal voltage transformers according to IEC 61869-11. In conjunction with a sensor adapter, conventional conversion transformers for current measurement as well as capacitive and precision dividers can be connected.
Fault detection
- directional short-circuit detection
- directional ground short-circuit detection
- directional ground fault detection with static and transient fault detection
- ground fault detection via pulse locating
- suitable for all neutral point treatments
- no summing transformer required
- fault recording
early fault detection
- detection of transient faults
- in conjunction with a CAPDIS- S2_55 (R5): Detection of partial discharges and their frequency and trend
Load flow measurement
- Voltages, currents, powers, frequencies, cos phi
- Momentary and average values
Comprehensive control and monitoring functions
- Control of motor controllers for switching load and ground switches
- Free programmable logic functions
