초록
A surge counter is installed under surge arrester, which is protecting the power system apparatuses against abnormal voltage and surges originated in power system line. A surge counter is the device of knowing the times of surge flowed in. There are two methods to get the electric power for mechanical movement and detect the surge. One is using ZnO varistor resister and the other is using the current transformer. In this paper, the characteristics of these methods are presented with using the test and evaluation of them. The process of evaluating the characteristics is essential to develop the domestic surge counter.
