Abstract

A method for treating cupric sulphide deposits on materials and surfaces being in contact with electrically insulating oil inside an electrical apparatus. The cupric sulphide deposits on materials and surfaces are subjected to treatment with a iodine compound causing a substitution reaction with the cupric sulphide.
