摘　　要：将大型冲击电流发生器运至现场,在实际的线路杆塔上给接地装置注入模拟雷电冲击大电流,测量接地装置对地电位升高、冲击接地电阻等指标,获得了运行中杆塔的接地装置冲击特性参数.同时应用接地装置仿真计算模型,按照与现场试验相同的条件用电磁暂态分析程序(ATP-EMTP)进行了仿真计算,将计算结果和试验结果进行了对比分析,取得了较好的一致性.The large impulse current generator was delivered to the site,and large simulation lightning current was injected into actual grounding devices of transmission line tower.The potential rise and impulse grounding resistance were measured,and the impulse characteristic parameters of the transmission line tower grounding were obtained.A simulation model of grounding was presented,and the simulation was taken by the ATP-EMTP（ATP-electromagnetic transients program）following the field tests.Comparison between the results of tests and simulation also is completed,and the consistency is good.
