  • Abstract
    The conditions required for the formation of copper sulfide originating from the DBDS oil additive which was identified by Scattigio (Terna, Italy) in 2005 is: "sufficiently high copper temperature" and copper corrosion will appear. This paper describes the findings when a transformer allegedly failed by corrosive sulfur was inspected with regards to the presence of copper corrosion. Strong corrosive attacks were found and their relation to temperature was very evident.
