Varistor is a metal oxide semiconductor nonlinear resistance element with zinc oxide as an important component. Resistance is more sensitive to voltage, when the voltage reaches a day, resistance quickly on. Because the varistor has outstanding non - line personality, large flow rate, low residual voltage level, fast path and no continuous current and other characteristics. It is widely used in lightning protection of electronic equipment.

Generally, lightning protection of power systems is divided into type B protection and Type C protection. The important role of type B protection is to deal with the strong lightning electromagnetic pulse disturbance and resist the lightning strike. The important role of type C protection is to realize the fine protection task after the type B crude protection, and to limit the transient overvoltage of the power system in the scope allowed by the electrical insulation. Usually, the harmony of these two levels can greatly improve the lightning protection level of the power system, so that the equipment in the lightning and drought gas safety task up double stability.
