Is there a lightning arrester that needs to be used?
Lightning protection device is actually a limiter, in parallel with the protected equipment near, when the discharge voltage over voltage line to upload more than lightning protection device, lightning protection device to discharge, will charge voltage wave into the underground, over-voltage damage propagation, thereby protecting other equipment from over voltage.
When lightning strikes the land near the line or the ground near the line, excessive voltage is generated on the transmission line, which is introduced into the electrical equipment by way of waves, and the safety of the emergency electrical equipment. In order to limit the amplitude of the invading wave overvoltage, the basic overvoltage protection device is the lightning protector.
Although the lightning rod can prevent lightning striking the electrical equipment, the protected electrical equipment is still damaged by lightning over-voltage.
