The Importance of Routine Fluid Analysis for Transformers

Five-step transformer oil testing process shown over a photo of a beaker of amber insulating oil. Curved arrows connect the steps in order: Dissolved Gas Analysis (DGA), Insulating Fluid Quality Assessment, Particle Analysis, Furan Analysis, and Diagnostic Evaluation.

Insulating fluid is the first place a developing problem with a transformer shows up. As utilities work to stretch aging transformer fleets further while managing tighter budgets, routine fluid analysis has become one of the simplest, most reliable ways to catch trouble early and keep equipment in service longer. At TJ|H2b, insulating fluid analysis is […]
