为预测非标准波形冲击下绝缘强度的积分法提供了理论依据。对于适用于气体、液体和固体绝缘的脉冲击穿的一般物理模型，以及适用于一般介质中的初始击穿通道的能量平衡模型，发展了两种理论方法。因此，将标准波形脉冲试验的数据作为输入，发现积分方法作为预测非标准波形绝缘强度的工具是相当成功的，这并不令人惊讶。给出的数值结果提供了对电压-时间曲线形状的理解。还使用了能量平衡模型来推导发生击穿后的通道的电阻。>；
A theoretical basis for the integration method of predicting the strength of insulation subjected to impulses of nonstandard wave shapes is presented. Two theoretical approaches are developed for a general physical model of impulse breakdown applicable to gaseous, liquid, and solid insulation, and from an energy-balance model applied to an incipient breakdown channel in a general dielectric. It is therefore not surprising to find that the integration method is reasonably successful as a tool for predicting nonstandard wave-shape insulation strengths, using as input the data derived from tests with standard-wave-shape impulses. Numerical results are presented that provide an understanding of the shape of volt-time curves. An energy balance model has also been used to derive the resistance of the channel after breakdown has occurred. >
