How Surge Protectors Work

222222 is divided into two types: explosion-proof box type and module type. Both use a varistor with excellent nonlinear characteristics. Under normal circumstances, the surge protector is in an extremely high resistance state, and the leakage current is almost zero, thus ensuring the normal power supply of the power system. When a surge overvoltage occurs in the power system, the power surge protector immediately turns on within nanoseconds, limiting the amplitude of the overvoltage within the safe working range of the equipment, and releasing the surge energy into the ground. Subsequently, the surge protector quickly changes to a high resistance state, so as not to affect the normal power supply.
