1. Solubility:
Insulating oils have a certain degree of solubility, which can dissolve pollutants in them, and have a certain degree of cleaning ability.
2. Antioxidant performance:
Insulating oils have good antioxidant properties, can antioxidants and thermal stabilisers, can resist the attack of free radicals and chemical reactions. This makes the insulating oil not easy to oxidise and deteriorate in the process of long time use, and keep the stability of its performance.
3. Examination Strategies
(1) Optical Inspection: Comprising an analysis of the oil's color, scent, transparency, and related visual features.
(2) Physical Parameter Evaluation: Determining the oil's physical properties, notably its density, flammability thresholds, and pourability for cold conditions.
(3) Chemical Analysis Protocol: Assessing the oil's chemical makeup by quantifying acidity, neutralizability, moisture, and gaseous components.
(4) Electrical Property Examination: Gauging the oil's electrical characteristics through measurements of dielectric losses, permittivity, and insulation strength.
