Abstract

This paper presents characteristics of the aged and new 18kV surge arresters. In order to investigate aging characteristics, we measured total leakage current and resistive leakage current using specially made leakage current measurement system and also investigated $tan{\delta}$ of the arresters and microstructure of the elements. Through the investigation we found that all of the arresters does not aged for 2 years field operation.
