  Correct use of ground rods

  The grounding rod is very flexible during construction, and different construction methods can be adopted according to the specific conditions of the site, such as directly driving into the soil with heavy hammers, electric picks and other equipment; under complex soil conditions, the grounding rod cannot be driven in, and can be drilled after drilling. Reinstall the ground rod. Diagram of the use method of ground rod When using a heavy hammer for construction under uniform soil conditions, if ...

  How to calculate the protection range of lightning rod

  Calculation of the protection range on the ground, calculation of the protection range of a single needle l In actual work, most lightning protection projects require lightning rods to be installed on the roof. Therefore, in order to apply the formula, no matter what the situation is, many people use the roof as the ground for calculation, which is not in line with the principle of the rolling ball method. The method of calculating the protection range of lightning rods using the roof as the gro...

  About the working principle of the lightning rod

  1. The working principle of the lightning rod: In the thunderstorm weather, when the charged cloud layer appears over the high-rise building, the lightning rod and the top of the high-rise building are induced with a large amount of charge. 2. Since the tip of the lightning rod is sharp, the tip of the conductor always accumulates the most charge during electrostatic induction. In this way, the lightning rod collects most of the charge. 3. The lightning rod forms a capacitor with these charged c...
