Interference Coefficient of X axis for Electrodes using Variation of Plural Earth Electrodes

In the building, there are a lot of electricity, electrodes, and communication equipment. Many of those equipment needs to earthing. Naturally, the earth electrodes are constructed in the site of a building. In such a situation, when electric current flows into a certain earthing system the potential of other earthing systems rises. That is, the potential interference will take place between the earth electrodes. The conventional study has been considered by only the relation of the distance between the earth electrodes using the potential distribution formula of earth surface. However, it is necessary to inquire strictly, taking the surface potential of electrodes by electrode form into consideration. In this paper, basic formula is deduced on the basis of both electrodes surface potential of earth electrode as a source of the potential interference and earth electrode which receives the potential interference.
