When lightning strikes a phase conductor of transmission line, the current will encounter the surge impedance of the conductor so that overvoltage will be built up and propagate to the substation along the transmission line in wave form.

当雷电击到输电线路的相导线上，电流遇到导线的波阻抗，这样就产生过电压，并以波的形式沿线路传至变电站。

It is not reasonable that striking distances of lightning leader to phase conductor, ground line and the ground are equal in classical electric geometry method.

针对经典电气几何模型认为雷电先导对导线、避雷线、大地三者之间击距相等的不合理问题，提出了用击距系数来描述雷电先导对导线与大地击穿强度的差别；依据长间隙放电与雷击放电的相似性，开展了棒-板间隙实验以得到击中目的物概率为50%时雷电先导与地面、导线之间的位置关系。
