Grounding is very important for electrical safety. But it is very difficult to secure enough space for the installation and management of grounding in the city because of the congestion of the buildings. Therefore, to solve this problem, this paper suggest structure-grounding application taking advantage of building structure as protective grounding. And, to verify its feasibility, this paper shows the result to measure and analyze grounding-resistance of structure for 12 buildings mainly structed in the city. |
