About high-voltage lightning arresters

High voltage surge arresters are usually installed in transmission lines and substations. Once lightning strikes, they quickly sense changes in the electric field and guide the high voltage underground through the connection of internal electrical components. In this way, the energy of lightning is dispersed underground, and electrical equipment and systems can be safe and sound!
Its working principle is really cool! By sensing changes in the electric field of lightning, high-voltage lightning arresters can quickly respond and guide high voltage underground, thereby protecting power equipment from lightning damage.
In addition to the power system, high-voltage lightning arresters are also widely used in communication systems and buildings. For example, in communication systems, high-voltage lightning arresters can protect communication equipment from the danger of lightning strikes; In buildings, lightning rods, a special high-voltage lightning arrester, can guide lightning to the ground and prevent damage to the building caused by lightning.
