From Data Collection to Insight

Modern substations generate vast amounts of data—temperatures, gas levels, vibrations, contact wear, and breaker operations. Historically, much of it went unused. Now, with advances in edge computing and AI, that data can be analyzed in real time to forecast failures before they happen.

A digital twin models the behavior of a physical asset, updating continuously with sensor input. When combined with machine-learning algorithms, it becomes a powerful tool for predictive...
