Grounding resistance of a transmission tower in Japan is commonly required to be less than 10 ohm to avoid lightning back flashover accident. However, it takes huge amount of cost to improve the resistance to the recommended value especially in the mountainous region. In order to reduce the cost of these works, the authors have investigated on flashover simulation with various grounding conditions. The paper deals with experimental results on grounding resistance of an actual 500-kV transmission tower footing and its downsized models. After brief review of necessity and scaling rule of the downsizing, we discuss dynamic characteristic of grounding resistance imposing very large current of 30kA.
