What is the filtration rate of transformer oil in power transformers?

The filtration rate of transformer oil in power transformers is crucial for maintaining oil quality and ensuring optimal performance. Typically, the filtration rate can vary based on the specific filtration system used, but it generally ranges from 1 to 5 liters per minute. This rate helps remove particulate contaminants and moisture, thereby enhancing the dielectric strength and longevity of the transformer oil.
