Significance of removing acidity in transformer oil

  Monitoring transformer for its fitness is inevitable to acquire uninterrupted power supply. Maintaining the good working condition of transformer oil protects the equipment from tripping and other failures. The wellbeing of the transformer is obsolete, if its transformer oil is contaminated, lest the apparatus would bulge or burst in the worst cases. Regular testing of the oil ensures safety and uninterrupted power supply while it serves insulation and cooling of the transformer. Though all oils are good insulators, vegetable oils and animal fats are not used in transformers since the fatty acids attack fibrous elements used in winding insulation. When transformer oil comes in contact with atmospheric oxygen it goes through chemical reaction which results in sludge or acid formation and settles in windings of the transformer. The oil deterioration that occurs deprives the insulating liquid of its cooling attributes and leads to expensive repairs. Oxidation and contaminat...
