What are the technical aspects of transformer oil cleaning?

The technical aspects of transformer oil cleaning involve several key processes, including filtration, dehydration, and degasification. Filtration removes particulate contaminants, while dehydration eliminates moisture, which can degrade insulation properties. Degasification addresses dissolved gases that can form due to electrical arcing or overheating. Advanced techniques such as vacuum treatment and the use of adsorbent materials enhance the efficiency of these processes, ensuring the transformer oil maintains its dielectric strength and overall performance. Regular monitoring of oil quality is also essential.
