What are transformer oil purification systems and how do they work?

Transformer oil purification systems are used to remove moisture, dissolved gases, and solid contaminants from insulating oil. These systems, like those offered by Fluidex, use high-vacuum chambers, heating, and fine filters to restore oil to its original specifications. They help industrial operators maintain transformer performance, improve breakdown voltage, and delay the need for costly oil replacement. Fluidex systems are suitable for both energized and de-energized transformers, and can be operated on-site.
