What is the lightning protection range of a lightning rod?
The lightning rod can not protect the low voltage lightning from the induction voltage on metal objects (such as telephone lines, power lines, etc.). It can only prevent the ground thunder from hitting the ground facilities directly.
As a matter of fact, the lightning rod itself is not a lightning rod, but a lightning bolt. It may lead to the landing of the mine. Its range of protection is highly related to its own height. A rough estimate is that the lightning rod can be used as the center, and a circle of 45 degrees from the tip to the ground can be drawn. The facilities in this range can not be struck by lightning.
Lightning rods can protect buildings with 45 degrees of angle, and it is unrealistic to protect the whole city. The principle of the lightning rod is to lead the mine and release it in advance, so the higher the lightning rod is, the bigger the scope of protection is,
