Improving Grid Reliability
Monitoring your grid is key to keeping the power network up and running. Our TE Kries grid monitoring and automation solutions enable to pinpoint faults and weak connections in the grid, providing an effective tool for power monitoring and asset management. They make the otherwise costly, labor-intensive upgrades on the entire grid unnecessary and consequently improve reliability, as measured by the System Average Interruption Duration Index (SAIDI).
Your Challenge: Fault Location
Locating a fault on hundreds of miles of power lines is a challenge for any distribution network owner. Disruptions to the grid caused by aging infrastructure, extreme weather events, wildlife interaction, demand growth for energy, or fallen conductors can cause power interruptions with high fault currents. These unplanned outages must be resolved promptly to minimize the impact on consumers – but locating a fault often costs time and money.

One Connectivity Partner
We carry more than 65 years of experience in cable accessories, and we offer a complete portfolio of TE Raychem switchgear connectors and terminations. They can fit virtually any cable size or installed product and offer reliable performance in the harshest environmental conditions.
Our acquisition of the German pioneering company Kries expands TE’s portfolio in power grid monitoring, protection and automation systems. For 30 years, Kries has been helping distribution network owners improve grid uptime and network efficiency effectively.
Our Raychem cable accessories, paired with our Kries devices, enable our customers to gain crucial data about their networks, helping to prevent failures and reducing both the System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI). Rather than deploying costly and labor-intensive upgrades on entire networks, grid monitoring devices can pinpoint faults and weak connections, providing an effective solution for a fraction of the investment. Our solutions can be integrated into new or retrofit projects.

Fault Indicators for Overhead Lines
Our Kries fault current indicators can be easily installed at strategic points throughout your grid. In the event of a short circuit, the IKI Overhead (IKI-OH) fault indicator sends an optical LED signal so grid operators can easily locate, repair, and restore power to the grid. We also provide a combination of communicating versions, the IKI-OH-Butler and IKI-OH-Radio, which allow remote reporting to a distribution control center. Our solutions help you to efficiently reduce unplanned power interruptions, thus improving grid reliability and resiliency.
Elevate grid intelligence with our Kries IKI-OH's real-time fault communication, empowering swift restoration. Its robust design, suited for diverse line conditions and weather, ensures reliability in maintaining optimal network health and safety.
Fault Indicators for Switchgears
Our Kries solutions help you maximize switchgear performance, improve grid transparency, and reduce grid downtime. Fault current indicators in switchgear offer real-time monitoring of electrical current flow, swiftly detecting and locating faults. They are crucial for maintaining operational safety and reliability. By identifying abnormalities like short circuits or ground faults, these indicators enable swift action to isolate faults, mitigating potential damage and downtime.
Voltage Detection & Partial Discharge
Our TE Kries voltage detection systems provide increased safety for personnel during on-site operations. In today’s complex energy distribution networks, particularly in medium and high voltage sectors, voltage detection is crucial for ensuring grid availability. Our Kries solutions offer secure voltage monitoring and detection, essential for enhancing system reliability. Modern voltage detection systems, easily installed using capacitive or ohmic sensors in any ring main unit, enable safe monitoring of voltage presence or absence. Additionally, ensuring the safety of staff working in hazardous conditions is paramount.
Smart Cable Accessories
Our Raychem separable connectors and our plug-in terminations are easy to install, compact, and adaptable to most cable types to reduce your installation time and costs. They are also compatible with our Kries monitoring devices.
