摘要

当雷击击中高大的物体，如传输和通信塔或变电站时，就会出现闪电瞬变过程。冲击产生的大电流在接地系统中流动并在土壤中消散。这种大电流产生的电磁场会对设备造成损坏，对人员有危险。应用场论方法研究了接地系统中雷电过程的瞬态特性。

Frequency domain analysis of 110/35 kV transformer station grounding system subject to lightning strike

Lightning transients processes appear when lightning strikes hit tall objects, such as transmission and communication towers or transformer substations. Large currents generated by the stroke flow in the grounding system and dissipate in the soil. The electromagnetic fields (EMF) generated by such high currents may cause damage to equipment and may be dangerous to personnel. The field theory method is used to examine the transient behaviour of the lightning processes in the grounding system.
