Lightning Arrester can effectively prevent the damage of induced lightning to a certain extent, but the effect will be affected by many factors.
Induced lightning is an overvoltage phenomenon caused by electromagnetic induction and electrostatic induction on nearby conductors when lightning discharges. The main function of Lightning Arrester is to limit the overvoltage within a certain safe range by releasing lightning current, thereby protecting electrical equipment from damage.
Under normal circumstances, when induced lightning is generated, Lightning Arrester can respond quickly and guide the overvoltage generated by induced lightning into the ground, thereby protecting the equipment connected to it. For example, in the electrical system in a building, the installation of a suitable Lightning Arrester can reduce the risk of damage to electrical equipment caused by induced lightning through wires, cables, etc.
However, the effect of Lightning Arrester in preventing induced lightning is not absolute. Its effectiveness depends on many factors. The first is the performance and parameters of Lightning Arrester, including its response time, discharge capacity, rated voltage, etc. If these parameters of Lightning Arrester cannot match the actual lightning environment and protection requirements, it may not be able to fully play its protective role.
Secondly, the installation location and number of Lightning Arrester are also crucial. If the installation location is unreasonable, such as being too far away from the equipment to be protected, or if there is not enough Lightning Arrester coverage on the critical path, the overvoltage generated by the inductive lightning may damage the equipment before reaching the Lightning Arrester.
In addition, the grounding condition of the system will also affect the effect of the Lightning Arrester. Good grounding can ensure that the Lightning Arrester can smoothly conduct the lightning current to the earth. If the grounding is poor, the lightning current cannot be effectively released, and the protective effect of the Lightning Arrester will be greatly reduced.
For example, in the power system of a large factory, if the rated discharge current of the Lightning Arrester is too small and the current generated by the inductive lightning is too large, the Lightning Arrester may be damaged due to being unable to withstand it and cannot effectively protect the equipment.
In summary, the Lightning Arrester plays an important role in preventing the damage of inductive lightning, but to ensure its effectiveness, it is necessary to reasonably select the type and parameters of the Lightning Arrester according to the specific lightning environment and the object of protection, correctly install and maintain it, and ensure a good grounding system. Only in this way can the role of the Lightning Arrester in preventing the damage of inductive lightning be maximized and the safe operation of electrical equipment be guaranteed.
