How are transformer oil analysis results evaluated?

Transformer oil analysis results are evaluated by examining key parameters such as dissolved gas analysis (DGA), moisture content, acidity, and furan analysis. DGA identifies fault gases that indicate insulation degradation or arcing. Moisture levels assess insulation integrity, while acidity indicates oil degradation. Furan analysis helps evaluate paper insulation condition. These results are compared against industry standards and historical data to determine the transformer’s health and predict maintenance needs. Regular analysis ensures optimal performance and longevity of the transformer.
