The transformer oil will age or deteriorate after a period of operation. In order to restore the performance of the transformer oil and maintain the safe operation of the transformer, it is necessary to filter the transformer oil at this time. The more economical and effective method is to use vacuum transformer oil filter, which has more advantages than centrifugal oil filter.

The performance of transformer oil is generally required as follows:

(1) The density shall be as small as possible to facilitate the precipitation of water and impurities in the oil.

(2) The viscosity should be moderate. Too low viscosity will affect the convection and heat dissipation, and too low viscosity will reduce the flash point.

(3) The flash point shall be as high as possible and generally not lower than 136 ℃.

(4) The freezing point should be as low as possible.

(5) The lower the content of acid, alkali, sulfur, ash and other impurities, the better, so as to avoid their corrosion to insulating materials, wires, oil tanks, etc.

(6) The oxidation degree shall not be too high.

(7) Stability should not be too low.
