Why purify transformer oil? Why need Transformer oil purifier machine? The majority of power transformers in operation today are filled with mineral oil. The primary function of the oil is to provide a high dielectric insulating material and an efficient coolant. The effectiveness of the oil as an insulating material is reduced as the moisture level increases, while cooling is reduced as the oil oxidizes. Paper insulation will also absorb moisture from the oil, thus increasing power factor readings.
