What equipment is used for transformer oil purification?

Transformer oil purification typically employs equipment such as vacuum oil purifiers, centrifugal oil purifiers, and filtration systems. Vacuum oil purifiers remove moisture and gases by creating a vacuum, while centrifugal purifiers utilize high-speed rotation to separate impurities. Filtration systems, including coalescers and adsorbent filters, effectively capture particulate matter and dissolved contaminants. These technologies ensure the transformer oil maintains optimal dielectric strength and extends the lifespan of the transformer.
