How does a transformer oil purification unit function in a generator?

A transformer oil purification unit functions in a generator by removing impurities and moisture from transformer oil, which is essential for maintaining the insulation properties and thermal conductivity of the oil. The unit typically employs processes such as vacuum distillation, filtration, and dehydration. By circulating the oil through these processes, the purification unit enhances the oil’s quality, ensuring optimal performance and longevity of the generator’s power transformer.
