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 to enhance its dielectric strength and longevity. The machine typically uses a combination of physical and chemical processes, including filtration, adsorption, and vacuum dehydration. Transformer oil is circulated through various filtration media, which capture particulate matter and absorb water, ensuring that the oil meets the required standards for optimal performance in power transformers.
