Method of diagnosing deterioration of insulating paper in oil-filled electric apparatus |
| abstract |
In a method of diagnosing the deterioration of the insulating paper in an oil-filled electric apparatus, the total amount of furfural is determined by adding the amount of furfural adsorbed on the insulating paper to the amount of furfural dissolved in insulating oil in an oil-filled electric apparatus, and the deterioration of the insulating paper is diagnosed by the correlation between the total amount of furfural determined and the polymerization degree of the insulating paper, which indicates the degree of deterioration thereof. The method thus permits the precise diagnosis of the deterioration of the insulating paper. |
