Title:
EARTH STRUCTURE OF EARTH SYSTEM AND POWER STATION
Document Type and Number:
Japanese Patent JP3261462
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To equalize the potentials of a lightning-struck position and positions apart therefrom, and prevent destruction of an apparatus by wiring plural conductors radially centering a building to an earth system buried under the ground which is electrically connected to a building.
SOLUTION: In earth structure which electrically connects a building and an earth system buried under the ground, the earth system is formed by wiring plural earth wires (a) taking a building as a center (o), and connecting earth resistors to outer end portions (b). In that case, it is desirable that plural conductors are connected to the radial conductors at the same radius positions taking the building as the center. Thereby, potential difference between a lightning-struck position and positions apart far away from the position can be suppressed as much as possible.
