What is the process of transformer oil filter machine and when is it required?

The process of a transformer oil filter machine involves the removal of impurities, moisture, and gases from transformer oil to restore its dielectric strength and ensure optimal performance. This machine typically employs techniques such as vacuum dehydration, coalescence, and filtration. It is required during maintenance, after oil contamination, or when the oil’s dielectric properties degrade, ensuring the longevity and reliability of power transformers in electrical systems.
