SF6 Gas Insulated Switchgear (GIS) so constructed that the main Conductive Parts are totally enclosed in metal enclosures which are filled with compressed SF6 gas. Present study examines a method for detection of the abnormal overheating caused by poor conductivity under the power supply conditions and for prevention previously of the internal faults leading to arcing which may be occured on such conductive parts.
In this paper, we propose the gas monitoring method which can permit the detection of not only the overheating conditions but also the events of gas leakage and the internal faults.
