A transformer oil purification plant works by processing contaminated transformer oil through several stages to restore its insulating and cooling properties. The process involves heating the oil to reduce its viscosity, passing it through filtration systems to remove solid particles, and using vacuum dehydration to remove moisture and dissolved gases. The degassing process further purifies the oil by removing any remaining gases. After purification, the oil is recirculated back into the transformer, ensuring it maintains proper dielectric strength and heat dissipation capabilities.
