摘要：

This paper describes the frequency dependence of the partial discharge characteristics in a needle-plane electrode system under sine wave applied voltage 50 Hz to 10000 Hz. We measured the pulse occurrence frequency, the maximum discharge magnitude, the φ-n distribution, the pulse mean φ-q distribution, and skewness of the φ-q distribution. We used the needle-plain electrodes with tip radius 30μm and 300μm at sine wave applied voltage of 1.25 kVp and 2 kVp. We found that the frequency dependences of these partial discharge characteristics are small. © 2017 The Institute of Electrical Engineers of Japan.
