What is the process of regeneration for oil in a transformer?

The process of regeneration for oil in a transformer involves the removal of contaminants and degradation products from the transformer oil. This is typically achieved through techniques such as vacuum distillation, adsorption, or filtration. During regeneration, the oil is heated and passed through materials that absorb impurities, restoring its dielectric strength and thermal properties. This process enhances the longevity and reliability of the transformer by ensuring the oil maintains its insulating and cooling capabilities.
