    Abstract: 氧化鋅避雷器其特性執行力於運轉過程中,常遭受突波電流、週遭環境因素如表面污染、水氣滲入、自然老化及溫度效應退化有絕對關係。如何掌握避雷器特性之良好與否,為運轉、維護部門所需解決之問題。
    The arrester, type zinc oxide, could be deteriorated by suffering from surge in power system and its ambient conditions such as pollution contacts on its surface, moisture penetration, temperature effects and long service time…etc,. Electrical engineers, work for substation, are responsible to keep eyes on the characteristics and performances of arresters .
    More important thing is to decide when to replace a busted arrester with a new one before a power fault occurs to the power system. There are several measurements available for the maintenance of zinc oxide arrester: surge counter, detection of total current leakage/resistant current leakage, temperature detected by infrared instrument and insulation inspection for arresters on a dead line .We would rather to say an appropriate and experienced technique utilized in inspecting the arrester is more important than to say which inspection way is better than another.
    By describing and evaluating the performances of arresters in substations and comparing its differences between traditional and modern preventive inspections, we acquire this paper with experiences from the measurements of local arresters in service.
