Overview of Research on Corrosive Sulfur in Transformer Oil

摘要

This paper gives an overview of research on corrosive sulfur in transformer oil.The mechanism of transformer failure due to corrosive sulfur,the test methods for total sulfur and corrosive sulfur,the source of corrosive sulfur,the basic groups of sulfur and sulfur compounds in crude oil,and possible mitigation techniques for cuprous sulfide formation are introduced.Additionally,potentially promising research topics on corrosive sulfur are discussed.
