Case Study: Statnett reduces transformer failure risk with Cognite Data Fusion™

How Cognite Data Fusion™ Helps Statnett Prevent Transformer Failure

Statnett, Norway’s national transmission system operator, worked with Cognite to improve transformer monitoring and maintenance. The challenge was to use data to detect early signs of transformer failure and reduce the risk of costly outages, repairs, and even fires across a large fleet of critical grid assets.

Using Cognite Data Fusion™, Cognite ingested transformer data such as temperature, load, dissolved gas analyses, technical specifications, and inspection logs into a single platform. Cognite helped Statnett build a health index for each transformer and visualize it in a dashboard for data-driven maintenance planning, contributing to an estimated $2 million in annual savings, a reduced risk of failure, and a goal of cutting transformer failures by 20–50% over five years.
