We have developed a new heating test to investigate the influence of dissolved copper (DBDS-Cu complex) and oxygen on copper sulfide generation in alkyl benzene insulating oil with dibenzyl disulfide (DBDS) added. The weight of the deposited and dissolved copper was systematically studied in atmospheres of nitrogen and artificial air. The copper sulfide was deposited on the insulating paper using...
