Determination of Sensor Position on 150 kV Gas Insulation Switchgear

Gas insulated switchgear is one of the important equipment in electric power system. Gas insulated switchgear can run into a malfunction that begins with the presence of partial discharge. Various methods have been developed to detect the presence of partial discharge. The most appropriate methods for detecting the presence of partial discharge in gas insulated switchgear is ultra high frequency method. In this study a simulation was conducted to determine the right placement of ultra high frequency sensor to obtain partial discharge signals accurately. The results of this study are expected to provide information about the proper sensor placement in diagnosing partial discharge on 150 kV gas insulated switchgear.
