摘要：

To prevent accidents through maintenance and appropriate replacement of oil-immersed transformer, the correlation between the life-time of the transformer was estimated by comparing the furan analysis of the insulation paper according to the accelerated deterioration and the insulating oil. According to accelerated deterioration, the furan value of DDP was reduced to about 1/1000 compared to that of Kraft paper, and it was shown that the thermal properties were excellent by the epoxy coating. As a result of the analysis of the degree of polymerization of the insulating paper, when the furan value was about 200 ppb, it was determined that the paper performance was lowered. Although the number of transformers collected is small, the life-time of the oil-immersed transformer is about 37 years. © 2021 Korean Institute of Electrical Engineers. All rights reserved.
