What is the working process of a transformer oil filtration machine?

The working process of a transformer oil filtration machine involves several stages to purify transformer oil. Initially, the contaminated oil is pumped into the machine, where it undergoes pre-filtration to remove larger particles. Next, the oil passes through a vacuum chamber, where moisture and dissolved gases are extracted. Finally, the clean oil is filtered through fine filters before being returned to the transformer, ensuring optimal performance and longevity of the power transformer.
