Moving beyond grid reliability: How Alliander optimized operations with real-time cable monitoring

In our electrified world, increasing demand strains distribution networks, raising the risk of cable failures and congestion. So how can you prevent outages, maintain grid reliability and optimize the operation of critical infrastructure? Watch this on-demand webinar, hosted by Sander Janssen, Business Director of DNV’s Smart Cable Guard and delve deeper into the world of real-time cable monitoring.

Alliander implemented real-time cable monitoring in 15% of their distribution cables. In 2022, this resulted in a SAIDI reduction of 2.14 minutes. Denny Harmsen, Consultant Innovation System Operations at Alliander (NL), shares insights into this project and explains how to leverage real-time cable monitoring to optimize maintenance strategies and prioritize resources effectively.

“One of our strategic pillars is excellent grid management by utilizing existing assets. Implementing Smart Cable Guard was the foundation to enable us to implement meshed operations and other innovative operational management concepts.”

Denny Harmsen, Alliander

A comprehensive explanation of real-time cable monitoring is provided by Paul Wagenaars, Product Manager at Smart Cable Guard. He guides you through the technology behind accurate fault and weak spot location. The presentation delves into the utilization of machine learning and artificial intelligence in assessing the criticality of emerging weak spots. Additionally, the importance of cable temperature measurement in optimizing grid capacity is discussed.

If you are a utility seeking cost-effective strategies to uphold grid reliability for critical infrastructure in an era of growing demand, this webinar is for you.
