| Summary: | 碩士 === 輔仁大學 === 電機工程學系碩士在職專班 === 104 === Metal oxide varistor (MOV), also known as surge absorber,will change its original characteristics with the increase of the suffering of surges, and the worse of the inhibition effect of surges has caused the interruption or destruction for the protection devices. But where can we know the ageing of the surgeabsorber?Obviously,the proper replacement will be a vital issue.
The thesis presents the testing and aging analysis for the specifications of MOV, that refer to the international certification standards related to surge protection device IEC 61643-1 and UL 1449 under the different test conditions and environmental requirements. The deviation of the variation of the leakage measured after the electrical characteristics aging tested. The tested results have shown the aging degree of surge absorber from the observation of the leakage currentmeasurements.
