전극형태에 따른 변압기절연유의 절연파괴에 관한 연구

In this paper, the breakdown phenomena of the transformer insulating oil were studied. Sphere electrode, needle electrode, plane electrode were used under uniform electric field . This paper studied the phenomenon up to the dielectric breakdown. Automatic dielectric breakdown tester was used to supply 2[kV] per 1[s]. In addition, the change of the electrode gap showed high breakdown voltage by increasing gap. It showed the highest breakdown voltage, when the sphere - sphere electrodes.
