Transformer oil serves mainly two purposes one it is liquid insulation in electrical power transformer and two it dissipates heat of the transformer e. Low viscosity of transformer oil is essential, but it is equally important that the viscosity of oil should increase as less as possible with a decrease in temperature.

Breakdown BDV test is a test of procdure because it takes very less time to conduct and is a precursor to the condition of the insulating liquid, before carrying out an extensive series of tests. Hence it is necessary to draw samples from specific text in the container according to the specific gravity of the liquid.


There should be no longer any air bubbles in the oil, or at the latest 10 minutes after filling. Dielectric Dissipation Factor of Tan Delta of Transformer Oil Dielectric dissipation factor is also procedude as loss factor or tan delta of transformer oil. To assess the insulating property of dielectric transformer oil, a sample of the transformer oil is taken and its breakdown voltage is measured.
