Case Study: a transmission system operating company extends transformer life by 5 to 8 years with Visplore

How engineers from asset management improved the reliability of a power transformer

The transmission system operating company faced a significant challenge with an unexplained malfunction in a critical power transformer, threatening the asset's health and leading to costly unplanned shutdowns. Their existing tools were insufficient for analyzing the vast amount of high-resolution sensor data to identify the root cause of the failure and prevent future occurrences. They turned to the vendor, Visplore, for a solution.

Using Visplore, the asset managers effectively investigated the data. The platform's tools for comparing time periods and its integrated formula engine allowed them to compute hundreds of derived indicators and automatically identify the most relevant sensors explaining the malfunction. This data-driven root-cause analysis enabled the company to identify harmful operating conditions and establish new monitoring indicators. The solution implemented by Visplore prolonged the transformer's life expectancy by an estimated 5 to 8 years and provided valuable insights for improving the reliability of other similar assets.
