Abstract

To realize the effective management of grounding resistances, it is necessary to establish a measuring technique of resultant resistance. Especially on underground system, it is too complex the connection of grounding system to understand the resultant resistance exactly by using of calculation, etc.
Therefore, we propose a new measuring technique of resultant resistance. That is the way to apply the voltage on two different circuits with auxiliary grounding electrode, and to measure each current of the route on the circuits. Additionally, we produced a test measuring equipment, and performed the verification on electric circuits, practice lines and commercial lines.
