Estimation of EPDM Insulator in Distribution Line Using PO and SO Measurement

PD 및 SD를 이용한 배전용 EPDM애자의 절연성평가

Many researchers make efforts to develop an effective material with anti-degradation property. Specially, the porcelain type insulator is required exchanging to polymer insulator according to the environmental consideration. In this paper, we have developed the estimation system using the PD & SD testing. Those approach has been very successful applied to the various practical insulator.
