고조파성분이 ZnO 바리스터 소자에 미치는 영향

초록

In this paper, in order to evaluate the effects of magnitude of applied voltage and harmonics on the performance of ZnO varistors, The resistance of ZnO varistor(20D431) was investigated as functions of the magnitude of applied voltage and the frequency 60 [Hz] to 540 [Hz] which responds to the fundamental and odd harmonics of 60 [Hz]-power frequency. As a consequence, it was fond that the resistance of ZnO varistor is decreased with increasing the magnitude and frequency of applied voltage.
