Assement of Surface Discharge for Polymer Insulator using High Frequency Current Transformer

고주파전류센서를 이용한 고분자애자의 표면방전 평가

Investigation of surface discharge characteristics of surface leakage on polluted EPDM insulatora have been performed This work was performed utilizing high frequency CT's to monitor surface discharge. It was found that there were significant variation in the surface discharge waveform frequency spectrum, depending both on the surface discharge magnitude and more importantly on the duration of surface discharge activity.
