The working principle of the arrester is based on the action of a parallel discharge gap or a non-linear resistor.
The working principle of the arrester is based on the action of a parallel discharge gap or a non-linear resistor. Under normal operating voltage, the arrester presents a high resistance state, only microampere current through. When the overvoltage effect, the resistance of the arrester drops sharply, and the energy of the overvoltage is discharged to achieve the protection effect. Different types of lightning arresters, such as tubular arresters, valve arresters and zinc oxide arresters, have different working principles, but they all use this basic principle to protect electrical equipment.
