Dielectric recovery of an axially blown SF6-Arc after current zero: part III-comparison of experiment and theory

A detailed comparison between experiment and theory is made on the basis of the results of Parts I and II. As a first step, a theoretical solution is derived which is based on experimental results for the turbulence onset and for the radial temperature profile at current zero. This solution is compared with the various measured data, e. g., the radius of the hot-gas channel as a function of time and the dielectric recovery characteristics. The influence of space-charge effects on the recovery are shown to depend on the time after current zero and the shape of the applied voltage. Recommendations for further research are made.
