Oil Used in Transformers and Maintenance of Transformer Oil. The MarketWatch News Department was not involved in the creation of this content. Oct 12, 2020 (Heraldkeepers) -- Transformers are considered as one of the most important equipment of the power network as their service in distribution of the generated power is most significant. Therefore, maintenance of such transformers become more responsible as sudden failures in transformer leads to heavy interruptions in power supply. The effective functioning of such transformers depends on the insulation condition of the equipment.
The quality of the oil used in transformers (Liquid insulation) determines the reliable working of the transformer and hence ensures the life of transformer. Transformer Mineral Oil: Mineral oil is mostly used as liquid insulation for power transformers due to their high heat transfer aspect also it serves as better coolant due to its high viscosity index.
