Electrical tree structure is one of the most important influencing factors for electrical treeing characteristics in polymers. In this paper, we focused on the structure characteristics of electrical treeing in epoxy resins (original) insulation under different high-frequency voltages (60, 500, 1000 ㎐). Effects of voltage frequency on the ac electrical treeing phenomena in an epoxy resins were carried out in needle-plate electrode arrangement. To measure the treeing initiation and propagation, and the breakdown rate, constant AC of 10 ㎸ with three different voltage frequencies (60, 500 and 1,000 ㎐) was applied to the specimen in needle-plate electrode specimen at 30 ℃ of insulating oil bath. At 60 ㎐, the treeing initiation time was 360 min and the propagation rate was 6.85×10-4㎜/min, and the morphology was dense branch type. As the voltage frequency increased, the treeing initiation time decreased and the propagation rate increased. At 1,000 ㎐, the treeing initiation time was 0 min and the propagation rate was 7.81×10-2㎜/min, and the morphology was dense bush type.
