    Transformer oil samples are analyzed by collecting a sample from the transformer and performing a series of tests to assess the oil’s condition. Common analyses include:

    Dielectric Strength Test: Measures the oil’s ability to withstand electrical stress without breaking down.
    Dissolved Gas Analysis (DGA): Detects gases dissolved in the oil, which can indicate internal faults like arcing or overheating.
    Moisture Content Test: Determines the amount of water in the oil, as high moisture levels can reduce insulation effectiveness.
    Acidity Test: Assesses the oil’s acidity level, which can indicate oil degradation or contamination.
    Interfacial Tension (IFT) Test: Evaluates the surface tension between the oil and water, which can indicate contamination.
