IKI-50_104

The universal Feeder Control Unit IKI-50_104 is the appropriate solution for intelligent distribution network stations and offers distribution network operators a high degree of transparency and cost-effectiveness. The IKI-50_104 includes all algorithms for selective fault detection. It is suitable for all neutral point treatments. Switching commands for load switch control can be fed to the IKI-50_104 via communication bus and executed field-related with 1.5-pole switching safety. The IKI-50_104 has an interface with IEC 60870-5-104 protocol, as well as a ModbusRTU master function for querying underlying measuring devices such as IKI-50.

Load flow measurement

• Voltages, currents, powers, frequencies, cos-phi …
• Momentary and average values
• Limit monitoring

Fault detection

• directional short-circuit detection
• directional earth fault detection, directional static earth fault detection (wattmetric method), directional transient earth fault detection (wiper method), earth fault detection via pulse locating
• early fault detection via detection of transient faults
• suitable for all neutral point treatments
• no summing transformer required

Network automation

• extensive logic functions freely programmable with PC- Software KriesConfig

Maintenance-free

• no battery
• unlimited data retention
• error indication in case of power failure over 6 hours

IEC 60870-5-104

• The device has a network connection for direct communication with control centers or telecontrol via IEC-104 protocol.

Webserver

• Configuration of the parameters for the IEC-104 connection via integrated webserver

ModbusRTU master function

• Modbus slave devices (e.g. IKl-50 in the standard version) can additionally be queried via the IKl-50_ 104. The conversion to IEC-104 is then also done in the device.

Security

•  Password protected configuration
•  Access rights management- Web server can be switched off- Encryption of the connection via VPN router possible
