Equipotential universal earth connection having a high current capacity

摘要

The subject of the present invention is an earth connection for an electrical installation. An earth connection according to the invention is characterised in that a conductor 2, buried in the ground, is a single conductor closed on itself in its prolongation at a looping point 1 in order to form a loop and in that an earthing conductor 3 coming from the overhead installation is connected tangentially to the said loop at at least one connection point 4; a third conductor 8 forms, together with the previous two conductors, an equipotential triangle in which the conductors are connected tangentially. Application of such an earth connection for the lightning protection of overhead electrical installations. IMAGE
