What is the process of oil processing for transformers?

The process of oil processing for transformers involves several key steps to ensure the transformer oil meets required specifications. Initially, crude oil is refined to remove impurities and moisture. This is followed by degassing, where dissolved gases are removed under vacuum conditions. Filtration is then performed to eliminate particulate matter. Finally, the oil is treated with additives to enhance its dielectric strength and oxidation stability, ensuring optimal performance in power transformers.
