초록

In this paper, the electrical characteristics of Insulating paper, for pole transformers, subjected to accelerated ageing were observed and the results were compared with those of virgin insulating paper. For the experiment, insulating materials for pole transformers were enclosed together in an oil bath and thermally aged under the real pole transformer operating conditions. After the accelerated ageing of the insulating materials, the dielectrics were measured and compared with the results of the virgin ones.
