gas in power systems has become a hot topic internationally. This paper used Pearson analysis to obtain 10 molecular electrostatic potential parameters that are strongly correlated with gas insulation strength. The conducts self correlation analysis on the 10 molecular electrostatic potential parameters to obtain 4 independent molecular electrostatic potential parameters. A structure-activity relationship model (4th order polynomial) was established using four molecular electrostatic potential parameters and gas insulation strength. The inverse Taylor formula method was used to obtain the functional relationship between each molecular electrostatic potential parameter and gas insulation strength. The influence mechanism of molecular electrostatic potential parameters on gas insulation strength was revealed, laying the foundation for finding a gas that can completely replace SF
