Transformer Oil Purification – Dehydration Vacuum Filtration Units

Transformer oil purification is a process to remove sludge, dissolve moisture and dissolved gases from the oil. Transformer oil conditioning may also include to some extent improving the acidity of the oil.

Advantages of transformer oil purification

Improved insulation properties of
the oil and hence the other media
like paper/cellulose insulation
Better insulation of the transformer prolongs the life of the transformer
and reduces breakdowns
A longer transformer lifespan delivers good returns on asset investments
Fewer breakdowns and failure of transformers result in uninterrupted power supply

Transformers are theoretically designed to last 300 years, the limitation to their life span is the deterioration of the insulation paper and the condition of the insulating oil inside the transformer Today majority of transformers are operating at a 25 % higher workload than recommended, this leads to gas production and faster deterioration of the insulation paper.

Annual testing and purification will ensure your transformers life is extended to ensure many years of service
