由附近雷击引起的电压是配电系统中停电的主要原因。我们计算这样的电压考虑到飞镖领导人的影响，随后返回中风在自然和火箭触发放电。结果表明，对于近似孤立的雷击位置，导线延长、先导电场变化对感应电压的幅值和形状有显著影响。考虑到在耦合机制中的领导者字段的结果在改进的协议之间的理论和实验感应电压数据从接近触发闪电在1986年获得的测试线在美国宇航局肯尼迪航天中心。
The voltages induced by nearby lightning strikes are a major cause of outages in power distribution systems. We compute such voltages taking into account the effects of the dart leaders that precede subsequent return strokes in both natural and rocket-triggered discharges. The results show that for stroke locations that are approximately alone, the line prolongation, the leader electric field change has a significant influence on the amplitude and shape of the induced voltages. The taking into account of the leader field in the coupling mechanism results in an improved agreement between theory and experimental induced voltage data from close triggered lightning obtained in 1986 on a test line at the NASA Kennedy Space Center.
