Another research topic is evaluated lightning induced voltages on nearby overhead-lines. Lightning is a transient, high-current discharge whose path length is measured in kilometers. During flash, neighbor electromagnetic field change violently, that would induce voltages on close-by metal.

另一研究课题为，非直击雷害造成邻近区域内架空线上的感应电压的探讨，雷击闪络可视为长距离的放电暂态现象，过程中会使得雷击周遭的电、磁场剧烈变动，将会在邻近的金属物件上感应出电压造成二次的伤害。

Combine with the analysis of the effect that caused by the shielding of topography and the conditions when lightning occurred on the top of the transmission tower, this paper bring forward a synthetical scheme that on the AnNan overhead transmission line, can use long life resistance reducer to reduce the ground resistance of the transmission tower,set up a shielding pull- line on the body of some tower,set up lightning arrester and take unbalance insulated method to improve the level of the line's ability of preventing lightning.

结合地面屏蔽效果分析和雷击杆塔塔顶情况分析，提出了在安南线采用降低杆塔冲击接地电阻、对部分杆塔塔身安装防雷拉线、加装线路避雷器、在双回路共架杆段采用不平衡绝缘配置等措施来提高安南线耐雷水平的综合方案。使用长效降阻剂，降低杆塔的接地电阻，这是提高线路耐雷水平、降低雷击跳闸率的有效措施。

In this paper, a brief analysis of the mechanism of overhead insulating conductor broken by lightning was introduced, and some detail information about the structure and principle of some anti-lightning broken device, such as over-voltage protector, arc-protection hardware and FLC-B lightning-protection hardware. And some electrical tests and analysis were done to these devices, after multi-comparison of those devices' performance, some specific measures are proposed against lightning broken.

Based on the discussion of some problems, it is pointed out that mountingadditional lightning arrestors on both ends of overhead lines is an effective means toprotect outlet CB of substations.

就事故分析提出了几个值得探讨的问题：事故与断口两侧有工频电源有关；雷击波的陡度值处于外绝缘大于内绝缘的区域和电压抽取装置的削波作用不显著而使灭弧室内绝缘击穿；外绝缘先击穿或内、外绝缘同时击穿；事故与雷击进线段发生绕击或反击的关系是主要的还是次要的。

Two factoids to remind you how dangerous lightning is: The air within a strike can reach 50,000 degrees F.
