Abstract
The impurities content of domestic hydrogenated transformer oil and three kinds of naphthenic transformer oil had been determined by using the specified experimental methods. A series of experimental data had been obtained, including mechanical impurities, particulate contamination, corrosive sulfur, sulfur content, total acidity and interfacial tension. The impurities content of four kinds of transformer oil were compared with the quality indicators of transformer oil on GB/T7595-2008. The results showed that the impurities content of the former was not so satisfying although it had excellent electrical properties and the technology needed to be improved.
