Transformer oil Filtration is a process to remove sludge, dissolved moisture and dissolved gases from the oil. Need for transformer oil filtration 1. Improved insulation properties of the oil and hence the other media like paper/cellulose insulationrn2. Better the insulation of transformer, longer the life of the transformer and lesser the breakdown of the transformerrn3. Longer the life of the transformer asset, good returns on investment of the assetrn4. Lesser breakdowns and failure of the transformer results in uninterrupted power supply
