Retrofit your installation into a smart grid and improve grid reliability with cost-effective solutions
The TE Connectivity (TE) Kries IKI-55 substation control unit is the advanced upgrade of the IKI-50, designed specifically for secondary substation applications ranging from 3 to 52 kV. The IKI-55 is an intelligent solution that addresses the evolving challenges of decentralized energy supply, and the increasing demands for power availability and quality in distribution networks. It provides unparalleled transparency, onsite or remotely, through a SCADA integration system, and is compatible with a wide range of communication protocols - ensuring seamless integration with various systems.
It can operate as a Modbus master providing robust control and monitoring capabilities. In addition to monitoring grid parameters such as voltage, current and power, the IKI-55 also supports power quality (PQ) and disturbance monitoring, enhancing overall grid transparency and reliability.
The IKI-55 allows the network owner to interact with a switchgear from a control center. It also allows to set an automatic switch in the case of unplanned outages or for maintenance, from one power feeder to another during unplanned outages or maintenance activities, thereby reducing operational costs and improving grid reliability.
It also ensures a continuous and reliable power supply through detailed, real-time data and robust fault management-elevating the efficiency and reliability of energy distribution networks.

Frequently Asked Questions
Question: What is a substation or feeder control unit?
Answer: This is a device which is used in electrical power distribution networks to monitor, control, and protect feeder lines. It ensures efficient and reliable power delivery by managing the flow of electricity and responding to fault conditions. However, it should be noted that IKI-50 and IKI-55 in particular are not protection relays, so if this is a requirement, then we also offer IKI-30 or IKI-35 as proper solutions to protect distribution transformer substations.
Question: Where should a feeder control unit be installed?
Answer: This type of units should be installed at key points in the distribution network, typically at substations or on feeder lines, to effectively monitor and control the flow of electricity.
Question: Can the IKI-50 detect the direction of a fault?
Answer: If the voltage signal is available, then IKI-50 can detect the direction of a fault. This is a helpful function when searching for faults in loop systems or in the case of missing information about the location of the transformer substations.
Question: What types of communication protocols are supported by IKI-50 and IKI-55?
Answer: IKI-50 supports Modbus-RTU protocols, whereas IKI-55 is able to support Modbus-RTU, MQTT, REST, and IEC 60870-5-104 - allowing seamless integration with various systems.
Question: Can IKI-50 and IKI-55 perform load management?
Answer: Yes, they can both manage and balance loads across the network which prevents overloading and ensures efficient power distribution.
Question: Can IKI-50 and IKI-55 integrate with SCADA systems?
Answer: These devices are designed to integrate with SCADA systems, providing real-time data and control capabilities to central operators.
