Abstract

The paper depicts a quantitative test method to determine the total corrosive or potentially corrosive sulfur concentration in electrical insulating oil. The method permits an objective approach for evaluating corrosiveness of insulating oils rather than subjective assessment relying on visual and subjective perception of color profiles that is prevalent in the current standard test methods for corrosive or potentially corrosive sulfur in insulating oils. The quantitative tests can provide additional information about the corrosive status of the insulating oils. In addition, this method permits an objective ranking of sulfur compounds according to their corrosivity towards copper materials.
