What is a transformer oil purification unit?

A transformer oil purification unit is a specialized system designed to remove impurities from transformer oil used in power transformers. This unit typically employs processes such as vacuum distillation, filtration, and dehydration to eliminate water, particulate matter, and gases. By enhancing the quality of transformer oil, the purification unit helps maintain the electrical insulation properties and overall performance of power transformers, thereby extending their operational lifespan and reliability.
