식물성 절연유의 열 열화에 따른 전기적 특성 연구

초록

This paper presents results of experimental investigations on natural ester regarding the breakdown strength. Aging of insulating material in a pole transformer has been studied by performing accelerated thermal aging test. Sealed aging test vessels containing copper, laminated core, Krapt paper and insulating oil(Natural oil and Mineral oil) were aged at for 30days. Compared to the conventional transformer oil, electric property of the natural ester fluid is excellent
