In this study. experiments were performed to measure the inception and breakdown voltages of SF6/CO2 mixed gases with varying mixing ratios at two different pressures (1 and 2 bar). Using the preliminary data obtained from the experiments. a 3D particle model was used to investigate positive streamer initiation in SF6/CO2 with field ionization. https://www.ealisboa.com/great-deal-Pentair-Union-Collar-2-U11-200PS-super-offer/
