What are the technical aspects of transformer oil additives?

Transformer oil additives enhance the performance and longevity of transformer oil by improving its thermal stability, oxidation resistance, and dielectric strength. Common additives include antioxidants, which prevent oil degradation, and corrosion inhibitors, which protect metal components. Additionally, pour point depressants improve low-temperature fluidity, while demulsifiers help separate water from oil. These technical aspects are crucial for maintaining transformer efficiency and reliability under varying operational conditions.
