Abstract
This paper deals with a development of the high precise measuring device of resistive leakage current for the deterioration and diagnosis of ZnO arresters. The resistive leakage current increasing with time leads to a thermally unstable state that may even experience a disaster. So, the resistive leakage current can be used as an indicator to discriminate whether the ZnO arrester blocks is in good state or in bad. The resistive leakage current measuring system with an analysis program operated with micro-processor using the time delay addition method was designed and fabricated. The proposed measuring systems for the resistive leakage current can effectively be used to develop the techniques of forecasting the deterioration of ZnO arresters in electric power systems. ⨀ ᔌ? 㔳㤮㈻Ԁ䭃䑎䷗ᜒं 6〰Ԁ䭃䑎䴀
