Explore the customer case
Explore how Xcel Energy, a prominent utility company, enhances its transformer fault assessment strategies by integrating a mobile online Dissolved Gas Analysis (DGA) monitor alongside traditional offline methods.
This case study highlights Xcel Energy’s experience using the Vaisala OPT100 DGA monitor on a mobile platform to analyze gassing patterns in transformers with abnormal lab-based DGA results.
By combining both methods and additional offline tests, Xcel Energy successfully diagnosed and managed a potentially problematic situation with a faulty transformer.
The study underscores the synergy of offline and online DGA analysis in making more informed and confident maintenance decisions, improving grid reliability, and optimizing asset management & safety.
