What is the transformer oil filtration process in power transformers?

The transformer oil filtration process in power transformers involves the removal of impurities, moisture, and gases from the insulating oil. This is typically achieved through a combination of physical and chemical methods, including vacuum dehydration, adsorption, and fine filtration. The process enhances the dielectric strength and overall performance of the transformer oil, ensuring reliable operation and extending the lifespan of the power transformer. Regular filtration is essential for maintaining optimal transformer health.
