  • The electrical characteristics of concrete block including a reinforcing rod in the foundation of the housing was fundamentally reviewed. It was tried to apply the substitutional earthing electrode in the foundation of the building. In order to identify the difference in the earthing resistance between mortar block and concrete block model, those models including a reinforcing rod in their inside were prepared and investigated for the earthing resistance. In results, the earthing resistance was largely affected by the block's resistivity compared to the change of resistance in reinforcing rods and the ground resistivity.

  • There are ground facility of maintenance in house electric facility of infra maintenance electric home appliances having used multifariousness in house, that use electric energy of common source for equipment. The body of building such as the reinforced concrete construction is structurally united, and the electric resistance is also small. It is possible that those foundations have contacted the ground at large surface area and that it substitutes the building construction body for the earth electrode. This is called "the structure earthing". This method has been defined at electrical facilities technical standards and KS in our country, and it has been used in various quarters practically. However, in our country, there is no example of using the foundation of the house as substitution earth electrode practically, and the means of the evaluation as electrode has not been established either. Then, in this paper, basic research for utilizing foundation of the house as substitution earth electrode is carried out.
