摘　　要：首先比较了不同试验所采用的雷电测量手段,而后介绍了雷电过电压在线监测系统,并且根据真型试验方案搭建感应雷试验系统,模拟雷击过程在线路上产生的感应过电压,采集到了多次感应过电压波形;最后仿真计算了真型试验工况下的雷电感应过电压,其结果与真型试验结果吻合性较好。The different methods of lightning measurement in different experiments are compared first. Then, the lightning overvohage online monitoring system is introduced. And the lightning induced overvoltage experiment system is set up according to designed experimental plan, which can imitate the generating process of the lightning induced overvoltage in overhead line. Finally, the lightning induced overvoltage in the condition of the real-model experiment is simulated, the results from simulation accord with the result from real-model experiment.
