Technology used :

High Vacuum, Low Temperature. Old technology of heating the oil at maximum temp. To remove water contact from oil was a big failure. In a research it was observed that heating the oil above 60 degree Celsius, started degrading the Cellulose of the oil. For efficient dry out, vacuum in excess of the equilibrium values is required. The drying operation occurs when the oil-cellulose equilibrium condition is disturbed favourably. We strongly recommend our customers for Recirculation of oil through the filter machine. The reason stays simple; the dry oil will be contaminated by the wet windings as they seek equilibrium condition, repeating this cycle many times can correct the situation.

Oil plays an important role in electrical transformers – in fact it is a dual role – as an electrical insulator and as coolant for the transformer. The active life of the transformer mainly depends on the quality of oil it contains. Regular transformer oil filtration assures long and consistent results from the transformer. Transformer oil purification is a process to remove sludge, dissolved moisture and dissolved gases from the oil. Transformer oil conditioning may also include to some extent improving the acidity of the oil. A good oil purification system is able to deliver filtered oil with parameters as per the standard specification.
