Identification of partial discharge sources in GIS using AEsensor

초음파센서를 이용한 GIS내 부분방전원의 식별

The use of ultrasound is proposed as the most economic and practical nondestructive test method for the detectin of electrical degradation in insulating materials. This paper has studied identification and characterization of partial discharge signals according to defects in GIS using AE(acoustic emission)sensor. Analysis of PD signals use $\psi-v-n$, skewness and kurtosis.
