Transformer oil analysis involves testing the oil for physical, chemical, and electrical properties. Key assessments include Dissolved Gas Analysis (DGA), moisture content, acidity level, and dielectric strength. The analysis detects signs of aging, contamination, and faults within the transformer, such as overheating or insulation breakdown. By interpreting these results, operators can make informed decisions about maintenance actions, potentially preventing failures and extending the transformer’s service life.
