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

The working principle of a transformer oil filtration machine involves the removal of impurities and moisture from transformer oil. The machine typically uses a combination of physical and chemical processes, including vacuum distillation, adsorption, and filtration. Transformer oil is circulated through various filtration stages, where contaminants are trapped, and moisture is evaporated, ensuring the oil meets the required specifications for optimal performance and longevity of power transformers.
