After lightning strike, the conductor can instantly induce huge voltage and current, causing damage to the electrical equipment in the building. Lightning rods can only prevent direct lightning and protect buildings. When it protects against direct lightning, it will also release a large number of induced lightning, which will instantly invade the interior of the electrical appliance along the antenna, feeder, signal line and power line, causing great damage to the electrical appliance, and the socket with lightning protection function can prevent the electrical appliance from being damaged by surge.
Lightning protection socket principle:
Whether the lightning protection socket is useful or not can actually be seen from the working principle of the lightning protection socket. The working principle of lightning protection socket is to install a lightning protection tube or varistor and other transient voltage absorbers between input lines to form infinite impedance. When transient voltage occurs, the impedance is rapidly reduced to transfer transient energy, thus achieving the effect of protecting internal electrical equipment. Therefore, the lightning protection socket can effectively absorb the surge pulse from the power supply system, so that the electrical appliances can be used safely in harsh environments and thunderstorm areas.
