The distance between the grounding device of an isolated lightning rod and the ground wire of the main grounding grid shall be no less than 3m. Which specification?
Distance between ground refers to the nearest distance between the grounding network of the grounding device of the independent lightning rod and the main grounding network between the transformer substation and the substation.
The reason is that "in", I think it is hidden after the completion of the project, from the surface to see is between the two grid distance, and this sentence "provisions of the lightning rod and the substation equipment space of not less than 5 meters distance" is a good check, the provisions "distance" and the ground link will be arranged underground network clear provisions.
Grounding device independent lightning and grounding in the distance should not be less than 3 meters, is to prevent lightning arrester, produce counter overvoltage and the provisions of the.
