How is transformer oil tested?

Transformer oil is tested using various methods to ensure its quality and performance. The primary tests include the Dissolved Gas Analysis (DGA) to detect the presence of gases that indicate electrical faults, the water content measurement to assess moisture levels, and the furan analysis to evaluate paper insulation degradation. Additionally, the physical and chemical properties of the oil, such as dielectric strength, acidity, and particle content, are evaluated using specific testers. Globecore provides advanced testers designed for these purposes, ensuring accurate diagnostics and maintenance of transformer oils. For comprehensive assessments, the “oc test on transformer” can be employed to monitor oil condition and ensure longevity.
