Detection of decomposition products is a widely studied method for condition diagnosis of SF6 insulated equipment because of its anti-electromagnetic interference and high sensitivity. A 90 L discharge chamber with adjustable defect was designed to simulate typical failures including metal protrusion defect, floating potential defect and insulator defect. Primary products of both the former two defects...
There inevitably exists trace level of water in the SF6 insulated equipment. Previous research has shown that the decomposition characteristics of SF6 has close relationship with the moisture content. In order to study the influence of moisture under low volume fraction on discharge and decomposition characteristics of SF6. An experimental and testing platform for SF6 gas-insulated electrical equipment...
