How does a wind turbine transformer oil purification system work?

A wind turbine transformer oil purification system works by filtering and degassing the oil to remove impurities, moisture, and dissolved gases. The system uses a combination of filtration stages, such as coarse and fine filters, to remove solid contaminants. It also employs vacuum degassing to eliminate moisture and gases. This purification process ensures that the oil retains its insulating and cooling properties, prolonging the transformer’s lifespan.
