As a general rule, the system grounding resistance should be less than 10 Ω. Multiple ground wires can be connected in parallel to connect to ground. The minimum distance between each ground wire is 5 meters. When measuring, use a megger. to connect one of the ground wires. , extend it up to 25 meters, measure the resistance and record. Then connect another ground wire in parallel and measure the ground resistance in the same way (the measuring wire is perpendicular to the ground wire connection wire). .
