Investigation of sensitivity of the ultra-high frequency partial-discharge detection technology for micro-crack in epoxy insulator in GIS

The ultra-high frequency (UHF) method has been widely used in a gas-insulated system (GIS) for partial-discharge detection, and many achievements have been realised. In addition, many studies based on artificial defects have been made to confirm its validity. Therefore, the UHF method is generally b...
