What are the technical aspects of transformer oil lab?

The technical aspects of a transformer oil lab include the analysis of oil properties such as dielectric strength, moisture content, acidity, and dissolved gas analysis (DGA). These tests assess the oil’s insulation performance and detect potential issues like overheating or arcing. Additionally, the lab conducts tests for oxidation stability and furan analysis to evaluate the condition of the transformer insulation system. Proper sampling and handling techniques are crucial to ensure accurate results.
