When a thunderbolt strikes a building, its huge current makes the building be exposed to a very high voltage. As a simulation experiment, we have performed a corona investigation of ungrounded model frameworks applied lightning impulse voltage, where the discharge images at the frames were observed with an image-intensifying camera. In a plane modeled framework of building, according to an increase in an applied voltage, the corona was generated from the part where concentrated the electric field to out side. On the other hand, the corona to the inside was controlled. The corona to the outside has expanded radially from the framework. As for this characteristic, this characteristic was obtained by the cubic modeled framework. The corona onset voltage of the cubic modeled framework is low, and that of the mesh type is high.
