单个绝缘子的电晕特性研究

Investigation on Characteristics of Corona Current of Single Insulator

用不同方法实验研究单个绝缘子电晕特性的结果表明绝缘子本身状态决定了电晕特性。据此提出了一种改进的N-（?）图法,可用于高压输电线路绝缘子串的在线检测。

In this paper, the characteristics of corona current with high voltage of a single insulator is studied in different methods. The results show that the characteristics of corona current are different with its status. From the characteristics of corona current, we can decide an insulator's status on-line.
