Main Structure and Operating Principle:
In the three phase four wire system, three phase lines and a neutral wire to ground are connected between the protector. Under normal circumstances, the protector is in a high resistance state, when the power grid due to thunder or other reasons out of the reason surge overvoltage, the protector will be immediately in the nanosecond time quickly conductive, the voltage overvoltage into the earth, thus protecting the power equipment on the grid. When the surge voltage through the protector, and disappears after the protector revert to a high resistance state, so as not to affect the normal operation of the grid
