A transformer oil purification system removes contaminants like moisture, gases, and particulate matter from the oil. The process typically involves heating the oil to reduce viscosity, passing it through filters to remove solids, and subjecting it to vacuum treatment to extract dissolved gases and moisture. Dehydration and degassing occur under reduced pressure, where water and gases vaporize at lower temperatures. Some systems use adsorption materials to capture acids and oxidation products. Purified oil regains its dielectric strength and cooling efficiency, improving transformer performance.
