What are the technical aspects of transformer oil reclamation?

Transformer oil reclamation involves several technical aspects, including the removal of contaminants such as water, sludge, and dissolved gases. The process typically employs vacuum distillation, filtration, and adsorption techniques to restore the oil’s dielectric strength and chemical properties. Additionally, monitoring parameters like acidity, moisture content, and furan analysis is crucial to assess oil quality post-reclamation. Proper reclamation enhances transformer efficiency and extends its operational lifespan.
