Retrofit your installation into a smart grid and improve grid reliability with cost-effective solutions
The TE Connectivity (TE) Kries IKI-50 substation control unit is tailored for switchgears and underground distribution and transmission lines from 1 to 52 kV. The IKI-50 is an intelligent solution designed to address the increasing challenges of decentralized energy supply as well as rising demands for power availability and quality in distribution networks. Designed for utility and industrial customers, it provides unparalleled transparency over network parameters such as voltage, current, and power - onsite or remotely, through a SCADA integration system.
Our IKI-50 not only monitors grid parameters from a distance, but also allows the network owner to interact with a switchgear from a control centre. It also allows precise voltage measurement and automatic cross-calibration along the entire secondary substation.
Engineered for durability, the IKI-50 is compliant with IEC and IEEE standards, and its design helps ensure consistent performance in harsh conditions from -25 °C to +75 °C, enhancing grid transparency and reliability while reducing costs.
Customers benefit from increased network transparency and proactive maintenance capabilities, resulting in faster fault resolution and reduced operational costs. The IKI-50 helps network owners provide a continuous, reliable power supply through detailed, real-time data and robust fault management, elevating the efficiency and reliability of energy distribution networks.
Locating a fault in underground networks involves time-consuming trial and error. Discover how directional fault detection delivers precise fault location and direction, reducing intervention time and accelerating service restoration.

Frequently Asked Questions
Question: What is a substation or feeder control unit?
Answer: This device is used in electrical power distribution networks to monitor, control, and protect feeder lines. It supports 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; if this is a requirement, we also offer IKI-30 or IKI-35 as appropriate solutions for protecting distribution transformer substations.
Question: Where should a feeder control unit be installed?
Answer: This type of unit 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 when information about the locations of transformer substations is missing.
Question: What types of communication protocols are supported by IKI-50 and IKI-55?
Answer: IKI-50 supports Modbus-RTU, whereas IKI-55 supports 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, preventing overloading and supporting 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.
