本研究的重点是局部放电起始电压和局部放电延迟时间的波动，直接关系到绝缘材料的物理性能。我们模拟的局部放电机制，并调查各种局部放电特性之间的关系。以这两种波动为参数，导出了描述局部放电特性的积分方程。通过针-板（NP）电极系统的局部放电特性实验和模拟实际电力设备中的缺陷部件的Monte Carlo模拟，验证了积分方程的有效性。
The focus of this study is on partial discharge inception voltage and partial discharge delay time fluctuations that are directly related to the physical properties of insulating materials. We model the partial discharge mechanism and investigate the relationship between various partial discharge characteristics. By considering these two fluctuations as parameters, an integral equation representing the partial discharge characteristics is derived. The validity of the integral equation through the experiments of partial discharge characteristics obtained using a needle-plane (NP) electrode system and Monte Carlo simulations that simulate a defective part in an actual power apparatus.
