Zusammenfassung:Disclosed is a method for predicting the amount of copper sulfide produced in an oil-filled electric device, including the steps of: (1) measuring the concentration(s) of one or more specific product(s) contained in an insulating oil collected from the oil-filled electric device; and (2) predicting the production amount of copper sulfide on the basis of the concentration(s) of the specific product(s). The specific product(s) is/include at least one compound selected from the group consisting of benzyl alcohol, benzaldehyde, benzoic acid, and dibenzyl sulfoxide.
