Recently, natural ester insulation (NEI) oils are found to be the best candidates to replace mineral-based insulation oils for oil-immersed transformer applications. However, NEI oilsare prone to oxidation due to their poor oxidative stability which can be improved by adding antioxidants into the oi...
