The oil testing done on the basis of different methods like IEC, ASTM, IS and other recognized transformer oils analytical procedure. There are 9 parameters in oil testing, these are:

Electric Strength (BDV)
Water Content (PPM)
Tan Delta
Resistivity
Acidity
Sludge
Flash point
Interfacial tension
Dissolved Gas Analysis (DGA)

Transformer oil is highly refined oil which works as an insulator. There is a very high temperature in transformer and this oil helps the transformer to remain cool and help to avoid any fire situation. The oil remains stable in high temperature and having great property of electrical insulation.

The oil in transformer must be pure and should be test once in a year. The oil must be moisture free and there should not be any other impurity.
