The Influence of Atmospheric Overvoltages on High-Voltage SF6 Substations [PDF]
, 2011 Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented ...

Dianci bileiqi, 2023 安装线路避雷器是输电线路最有效的防雷方法之一，常规的避雷器安装方式未考虑实际杆塔的结构、地形以及闪络成本等问题，导致技术经济性较差，存在一定的盲目性。为研究避雷器的经济性安装方案，基于ATP-EMTP与电气几何模型建立了同塔双回杆塔电磁暂态分析模型。研究了杆塔结构、地形地貌对双回线路闪络风险的影响，并考虑线路闪络成本对避雷器安装方式的影响，提出利用技术经济性指标W对避雷器不同安装方式下的防雷效果和经济性进行综合评估，当W>0时，避雷器安装具有经济性，W值越大，技术经济性越强。
