Transformer Oil Filtration Plant

As is well known the Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as a effective dielectric. Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. TRUHEAT oil purifier is the most efficient and economical purification system. It consists of the following:
1) Filter Unit : The filter unit consists of:
(a) a Coarse strainer having a wire mesh filter element for retaining solid particles and a powerful magnet for retaining magnetic particles.
(b) a Filter unit containing round type filter paper discs held under spring compression. These can be easily cleaned off the sediment by reverse flow of compressed gas.2) Indirect system of Oil Heating : Specially designed heaters with low watt density heat the auxiliary heating oil, which in turn heats the transformer oil maintaining a temperature of 70-80 C. This indirect method of heating completely obviates any localized overheating of transformer oil.
