  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 The wellbeing of the transformer is obsolete, if its transformer oil is contaminated, lest the apparatus would bulge or burst in the worst cases.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...

  The increasing demand for electricity has taken a toll on transformers which are burdened with stress and overheating and result in breakdowns. The significance of maintaining the  transformer insulating oil  in good condition and mitigating  oil deterioration  has been widely acknowledged in the industry. Ageing of transformers have received increased focus in the recent past, owing to their relation with oil deterioration and  oil regeneration system  of  transformer insulating oil. When oil and paper, the two main players of insulation, age, they produce acids and moisture. Such by products must be identified and removed so that ageing is controlled and longevity is enhanced. Besides, measuring these byproducts reveal intensity of the ageing process. Acidity and humidity of the paper enlightens about the ageing that the cellulose insulation went through. The physical, chemical and functional attributes of  transformer insulating ...
