How do you remove moisture from transformer oil?

To remove moisture from transformer oil efficiently, you can utilize several methods, including vacuum dehydration, which involves applying a vacuum to lower the boiling point of water in the oil, allowing it to evaporate; centrifugal separation, which uses centrifugal force to separate water from the oil; and using a suitable drying agent or desiccant, which absorbs moisture from the oil. Additionally, proper filtration can help in capturing any suspended water particles, ensuring the transformer oil is kept at optimal moisture levels to maintain the performance and longevity of the transformer. Regular maintenance and monitoring of moisture levels are crucial for preventing degradation of transformer oil and ensuring reliable operation.
