Under normal circumstances, the protector is in a high resistance state, when the power grid deals with surge overvoltage due to lightning strike or other reasons, the protector will turn on quickly within nanoseconds, and introduces the voltage overvoltage into the ground, thus protecting the electrical equipment on power grid. When the surge voltage passes through the protector and disappears, the protector changes to a high resistance state again, so as not to affect the normal operation of the power grid.
