초록
In this work, a novel semi-internal type UHF PD sensor has been proposed and related investigations has been performed in order to detect the partial discharges that could be possibly produced at the insulation system of the gas insulated switchgear(GIS). This sensor was designed to mount on the CT terminal hole of GIS using the spiral antenna theory. Therefore this type sensor can be install on GIS during the power apparatus has been operation and better sensitivity compare to the commercial external type UHF PD sensor.
