Experimental Investigation of the Mixture of Sulfur Hexafluoride and Nitrogen in pulsed regime

Sulphur Hexafluoride SF6 is an insulating gas widely used in the pulsed power industry. However, it is a strong greenhouse gas with a potential impact 23000 higher than that of CO2. We propose alternative methods to minimize the use of SF6 while maintaining part of its dielectric strength, required to prevent breakdowns. Based on experimental results of different SF6-N2 mixtures, we show that a more environmentally friendly solution can be obtained.
