Summary:A GIS isolation switch high frequency arc resistance model modeling method, a high frequency arc consisting of three stages: a pre-penetrating stage, an arc burning stage, and an arc extinguishing stage; arc resistance reduces exponentially in the pre-penetrating stage, is stable in the arc burning stage, and steadily increases exponentially in the arc extinguishing stage. The influence effect on the arc resistance by a steady state arc resistance, current peak value, barometric pressure, and arc length is obtained and a steady state arc burning resistance mathematical model is established via an SF 6 gap high frequency arc test; a real-time pattern and parameter of the arc resistance is obtained, and a GIS isolation switch arc resistance dual-exponential real-time mathematical model is established via a GIS isolation switch hot line work operation; by simulative calculation on high speed transient voltage generated by the GIS isolation switch hot line work operation, comparing to the result of the GIS isolat
