Influential Parameters in Lightning Current Passing a Grounding System of High Voltage Substation

The voltage amplitude and its distribution along the grounding grid are decided by current injecting a grounding system of high voltage substation [1]-[2]. Therefore, the short circuit current passing this grounding system of substation is always cared by the designers. [8]-[9] introduced a new method to calculate the current passing grounding system of high voltage substation when lightning strikes on the grounding wire of transmission line at any point regardless of the influential parameters. This paper studied clearly the influence of the parameters of “grounding wire-electric pole system” and from this, the dangerous zone of high voltage substation and some other interesting results were received....
