The metal-oxide (ZnO) surge arrester is an over-voltage protecter,for electric power system. The arrester protects electrical equipment such as transformer with correspondent voltage gradation, commentating capacitor, etc.from insulation breakdown of temporary over voltage, lightning over-voltage and operating over-voltage. The arrester is characteristic of good steep wave response, high flux of current, low protective residual voltage, non-operating frequency splicing current, small volume and good maintainability, etc.
