How does a wind turbine transformer oil gas removal system function?

A wind turbine transformer oil gas removal system functions by creating a vacuum environment in which the oil is heated. This lowers the pressure inside the system, causing dissolved gases such as oxygen, nitrogen, and hydrogen to evaporate and escape from the oil. The gases are then removed from the system through a vacuum pump. This process helps improve the oil’s dielectric strength, reducing the risk of electrical discharges and ensuring stable transformer performance.
