Abstract

In this work, in order to investigate the effect of lightning impulse currents on ZnO surge arrester. and the deterioration characteristics of ZnO surge arrester, 8/20 [${\mu}s$], 2.5 [kA] impulse currents were applied to the ZnO surge arrester under test. The leakage currents of ZnO surge arrester were measured and ZnO element was analyzed by X-ray photoelectron spectroscopy. As a result, the resistive leakage current of ZnO surge arrester was increased with the injection number of lightning impulse currents.
