    Oil testing on transformers is performed by taking a sample of the insulating oil and analyzing it in a laboratory to assess its condition. Common tests include:

    Dielectric Strength Test: Measures the oil’s ability to withstand electrical stress without breaking down.
    Dissolved Gas Analysis (DGA): Detects and measures gases dissolved in the oil, which can indicate internal faults such as arcing or overheating.
    Moisture Content Test: Determines the amount of water in the oil, as moisture can reduce insulation effectiveness.
    Acidity Test: Assesses the oil’s acidity level, with higher acidity indicating degradation or contamination.
    Furan Analysis: Detects degradation products of the paper insulation within the transformer, indicating the health of the solid insulation.
