Direct lightning is extremely severe for power lines. There are many grounding objects, such as reinforced concrete buildings and trees, around distribution power lines. It is considered that the grounding objects have a shielding effect on direct lightning. In this paper, the shielding effect of the reinforced concrete building on direct lightning to the distribution power line has been studied by an experiment on a reduced scale-model and electro-geometrical model. Particularly, the effect of shape of the building edge on the shielding to direct lightning have been investigated in this research. From the experiment, 50% flashover voltage for negative applied voltage is affected by the shape of the building edge. Consequently, calculation results by the electro-geometrical model show that the shielding effect for negative lightning is influenced by the shape of the building edge.
