What is the procedure for transformer oil testing methods and what parameters are evaluated?

The procedure for transformer oil testing involves several methods, including Dissolved Gas Analysis (DGA), Furan Analysis, and dielectric strength testing. Key parameters evaluated include moisture content, acidity, dielectric breakdown voltage, and the presence of dissolved gases. These tests help assess the oil’s condition, detect potential faults, and ensure the transformer operates efficiently and safely. Regular testing is essential for predictive maintenance and prolonging transformer life.
