Why is the distance between the independent lightning conductor and its protected object too small?
The individual lightning rod has protective limits for the following protection. Within the range of specific calculations, refer to various power design manuals.
When the lightning arrester, lightning current arrester through the great earth, this current will lead in the lightning rod form a large voltage line, if the protected object distance of lightning induced voltage in line will breakdown and protected objects between the air, caused two counter attack. China's design regulations: to prevent the two counterattack in the air distance of 5 meters, 3 meters in the ground.
When the protective device is outside the protective range of the lightning rod, the protective material is protected from being protected, so that the protection can not be too far away from the lightning rod.
