摘要
In this paper, the property of the partial discharge, frequency and temperature dependence of dielectric property are tested in the electrical aging duration. It is shown that there are two kinds of partial discharge in high voltage ceramic capacitor. With the aging time increased, one's initial discharge voltage goes down continuously, and its dielectric spectrums have got changes obviously. The other's initial voltage has a rise up to the aging voltage at first, then it goes down to a constant and its dielectric spectrums have few changes. On the base of above, the affection of the partial discharge to the electrical aging property of high voltage ceramic capacitor is concluded.
