本文报告了利用雷电过电压的计算机模拟对配电线路雷电性能进行的研究。先前研究的结果通过附近冲程的感应电压的详细模型进行了扩展，并耦合到现实的电力系统模型中。本文还考虑了暴露于直接冲击的配电级避雷器的能量负荷。主要结果是，广泛分离的杆顶避雷器可以有效保护配电线路免受感应电压闪络的影响。这意味着对于大多数配电线路来说，附近的雷击不一定会成为严重的雷击性能问题。 >
This paper reports a study of distribution line lightning performance, using computer simulations of lightning overvoltages. The results of previous investigations are extended with a detailed model of induced voltages from nearby strokes, coupled into a realistic power system model. The paper also considers the energy duty of distribution-class surge arresters exposed to direct strokes. The principal result is that widely separated pole-top arresters can effectively protect a distribution line from induced-voltage flashovers. This means that nearby lightning strokes need not be a significant lightning performance problem for most distribution lines. >
