How do transformer oil filtration systems work?

Transformer oil filtration systems work by removing impurities and moisture from transformer oil to maintain its insulating properties and extend the life of the transformer. The system typically consists of a filtration unit that uses a combination of mechanical filters and vacuum dehydration processes. The oil is circulated through these filters, where particulates are trapped, and moisture is evaporated under reduced pressure, ensuring the oil remains clean and effective for optimal transformer performance.
