영문 초록

In this paper, we are doing research on the effects of the injected number and amplitude of surge current on ZnO varistor limiting voltage versus change of injected surge current(10/350μs). We injected surge current under the same conditions until the varistor totally broke down and then took a measurement of voltage at that time. We analyze characteristics of surge currents on the performance of ZnO varistor, the measurement of voltage before and after the injection of the same surge current. As a consequence, the amplitude of average limiting voltage through ZnO varistor were increased with increasing surge currents. And we found that the number of injection on the surge current was increased for lower surge current.
