Overview
Increase reliability and minimize downtime by monitoring faults and earth faults on single phase conductors up to 52 kV

The TE Connectivity (TE) Kries IKI-10 fault and earth fault current indicator is designed for switchgears and underground distribution and transmission lines from 3 to 52 kV. Efficient fault detection and immediate response are crucial for maintaining the reliability of your power grid. Our Kries IKI-10 fault indicators are designed to monitor fault conditions such as short circuits, temporary disruptions and ground faults on single phase underground power grids, helping grid operators to quickly restore power after unplanned outages.

 

The Kries IKI-10 is equipped with integrated LED indicators for immediate fault detection, ensuring rapid response time and minimal damage. It is engineered for durability and is compliant with IEC and IEEE standards, while its design ensures consistent performance in harsh conditions from -25 °C to +75 °C (-13 °F to +167 °F) - which enhances grid reliability and reduces costs. Additionally, the IKI-10 has an integrated battery, ensuring continuous operation and fault detection even during power outages, and further improving system reliability and safety.

 

Designed for seamless integration, the IKI-10 fits easily into existing systems with minimal disruption. The user-friendly installation process allows for quick setup and configuration, enabling immediate benefits in both grid reliability and reduced downtime.

FAQ

Frequently Asked Questions

Question: What is a single-phase fault current indicator?

Answer: A single-phase fault current indicator is a device which is used to detect and indicate the presence of fault currents (such as short circuits or earth faults) in a 1-phase or 3-phase electrical system.

 

Question: How does the TE Kries IKI-10 fault current indicator work?
Answer: This type of device uses sensors to detect abnormal current levels in the zero-sequence current, and then provides a visual or electronic signal when a fault is detected - helping to quickly identify the location of the fault.

 

Question: What types of faults can IKI-10 detect?​

Answer: It can detect short circuits, ground faults, and other abnormal current conditions, in a 1-phase or 3-phase electrical system.

 

Question: Can the fault current indicator be used in outdoor environments?

Answer: Some models are designed for outdoor use and are weatherproof, but it's important to check the specific both the IP rating of each specific model.

 

Question: What maintenance does the TE Kries IKI-10 require?

Answer: To ensure proper operation, sensors and display units should be kept clean, and regular inspections are required. Periodic testing, as recommended by the manufacturer, should also be carried out.
