Different transformer oil tests include:
Dielectric strength test: Measures the oil’s ability to withstand electrical stress without breaking down.
Dissolved gas analysis (DGA): Detects gases produced by oil degradation or electrical arcing, indicating potential faults.
Moisture content test: Assesses the amount of water in the oil, as high moisture can reduce insulation effectiveness.
Acidity test: Determines the oil’s acidity level, with higher acidity indicating aging or contamination.
Interfacial tension (IFT) test: Evaluates the oil’s surface tension, which can indicate contamination or oxidation.
Furan analysis: Detects furans in the oil, which are byproducts of paper insulation degradation.
