what is transformer oil filtration?

Transformer oil filtration is a process used to remove impurities, moisture, and gases from insulating oil in transformers. This is crucial for maintaining the oil’s dielectric strength and overall performance. The filtration process typically involves using specialized equipment, such as vacuum dehydrators or filtration units, to ensure the oil is clean and free from contaminants. Proper filtration enhances the longevity and reliability of transformers, preventing failures and ensuring efficient operation.
