Abstract :
Removal of dibenzyl-disulfide (DBDS) from a mineral oil of an in-service transformer was found to greatly reduce the overall corrosive sulfur content of the oil. In addition, a very significant improvement was also obtained in the acidity, surface tension, and to some degree in the dielectric loss characteristics of the mineral oil.
