The study indicates that:install MOA at line side is the most effectiveness method to protect banked switch,keep up the tower dielectric level will increase the probability of lightning stroke, but it can reduce the amplitude of lightning intrusive waves, this is advantage to the protection of the substation ,and lightning protective effect of this mode is the best.

研究表明：在开关前安装MOA是保护热备用开关的最有效措施，即使在最严重的情况下，热备用开关的绝缘裕度也超过10%，可以保护开关的正常使用；不增加进线保护段杆塔的绝缘水平会增加进线保护段的雷击概率，但是此措施可以降低入侵波的幅值，对变电所防雷有利，这种防护方式的防雷效果最好。
