Abstract: A SWNT-uhf combined sensor and gas insulated switchgear using the same is provided to secure high sensitivity detection while realize measurement frequency band of the UHF sensor in low cost. A SWNT-UHF combined sensor and gas insulated switchgear using the same is comprised of steps: sensing harmonic generated inside of the GIS by utilizing a UHF sensor(S101); sensing more than one of ion of the SF6 gas or products which are disassembled to the ion by utilizing the SWNT sensor(S102); deciding whether partial discharge of the GIS is generated or not based on the UHF sensor and the result of the SWNT sensor.

Abstract: An apparatus and a method for detecting partial discharge at SF6 GIS(Gas Insulated Switchgear) using a single walled carbon nano-tube are provided to previously detect an abnormal effect by using a single walled carbon nano-tube as a partial discharge sensor of SF6 GIS. A method for detecting partial discharge at SF6 GIS is characterized in that a plurality of single walled carbon nano-tubes(2) are installed in an inside of a GIS case(1) in order to detect partial discharge, namely SF6 plasma or ions and radicals generated in a dissociating state of SF6 gas. The single walled carbon nano-tube is a carbon nano-tube which is manufactured by using a HipCo(High Pressure Carbon Monoxide) method.
