Transformer Oil Filtration Systems

Flower Westrup (India) Limited are pioneers in the field of filters and filteration Equipment. Set up in technical collaboration with "STREAMLINE" filters, a division of the world renowed "Vokes Limited", U.K., they have been manufacturing Insulating Oil Conditioning Plants for the past 22 years. They have also entered into a technical collaboration with "MICAFIL" Switzerland for manufature of ultra high vaccum filters. These plants manufactured originally under the brand name "Streamline Filter: and subsequently under the brand name "Nirmal Filter" have been giving excellent service to Electricity Boards, Nuclear power stations, Transformer manufacturers and other customers all over the country.
  Transformer Oil :-
All high capacity transformers in use today have to cope with voltages in excess of 400kv. therefore it becomes imperatine to maintain insulation properties of the transformer oils by rigid control over moisture, dissolved gases and particulate contamination. Transformer oil is in an environment that lead to degradation in its desired properties and even in a proactive maintenance programme, transformer oil will lose its insulating & cooling properties over a period of time. The rating requirements and drive to tighter tolerances of modern transformer and electrical apparatus results in greater electrical stress in insulating material and fluids. To handle these stresses, oils are required to have better dielectric strength, and also lower residual water content must be maintained to reduce the speed of oil ageing. The periodic and proper treatment of these insulating fluids will result in the improvement of properties of the entire insulating system of power transformers and will extend the effectivee lifetime of the asset.
  Function Of Oil In Electrical Equipment :-  
  • Used as cooling media
  • Used as dielectric media
  • To isolate winding from atmosphere
  • To quench the arc
  Contaminants Of Oil :-  
  • Soild particles like rust, scales, dust and fibers.
  • Generation of carbon particles due to ageing in switchgears
  • Oil absorbs moisture resulting in free and dissolved water.
  • Absorption of air.
  • Absorption of gases.
  • Sludge formation.
  • Increase in acidity level.
  Effects Of Contaminants On Oil :-
Color Not Clear, Turbid, Hazy Increase In Neutralization Value Low Di-Electric Strengh
Low Interfacial Tension   Low Resistivity
Decrease In Flash Point   Increase In Tan Delta Value.
