    Testing involves:

    Sampling: Collecting oil samples from the transformer using clean procedures to avoid contamination.
    Dielectric Breakdown Voltage Test: Measures the oil’s insulating capability.
    Moisture Analysis: Determines water content using methods like Karl Fischer titration.
    Dissolved Gas Analysis (DGA): Detects gases that indicate thermal or electrical faults.
    Acidity Measurement: Assesses the level of acidic compounds formed due to oxidation.
    Particle Count Analysis: Evaluates the cleanliness of the oil.
    These tests help identify degradation or contamination, guiding maintenance decisions.
