Current injecting a grounding system of high voltage substation decides the amplitude and the voltage distribution along the grounding grid [1]-[2]. Therefore, the determination of short circuit current at substation is always cared by the designers. This paper presents a method to fast calculate the current passing through grounding system of high voltage substation when lightning strikes at the grounding wire of transmission line.
