How do transformer oil purification systems operate?

Transformer oil purification systems operate by removing impurities, moisture, and gases from transformer oil to enhance its dielectric strength and extend the lifespan of the transformer. These systems typically use a combination of filtration, vacuum distillation, and adsorption processes. The oil is heated and passed through filters to remove solid particles, while vacuum conditions facilitate the removal of dissolved gases and moisture, ensuring the oil meets the required quality standards for optimal transformer performance.
