How is wind turbine transformer oil filtration performed?

Wind turbine transformer oil filtration is performed using multi-stage filters that remove solid contaminants such as dirt, sludge, and metallic particles. Coarse filters capture larger particles, while fine filters target smaller contaminants. The oil is circulated through the filtration system, which continuously removes impurities. Regular filtration ensures the oil’s insulating properties remain intact, reducing the risk of transformer malfunctions.
