| Abstract: | The source and harm of moisture content in SF_6 gas insulation equipment were briefly described, and the limited index of general SF_6 gas moisture content defined by relevant department and the measurement method for SF_6 gas moisture content was introduced. The working principles of online inspection element taken the humidity sensor of high polymer film capacitance type as relative humidity (RH) were elaborated. The online monitoring of moisture content for SF_6 gas insulation switch were put forward, which can not only carry out effective control for insulation gas of high voltage switch in operation, at the same time, also offer the favorable basis for condition based maintenance. |
