SF6 is a commonly used insulating gas for power equipment,and its greenhouse effect potential is 23 900 times that of CO2,which has a non-negligible effect on global warming.The current SF6 recovery process in power systems has difficulties in determining the recovery rate,gas chamber volume,and recovered gas volume data.In this paper,a set of power system SF6 gas online detection method and its supporting detection sensor are designed according to the Betty-Bridgman empirical equation.And the method was validated us-ing the weight method with a known volume container.The results show that the error of this method is less than 2%,and it is capable of accurate and rapid determination of SF6 gas data.It can provide a reference for related practitioners in the power industry.
