The aim of this work is to compare the main characteristic of good dielectric gas defined in our previous paper with nitrogen gas. We study the molar fraction of chemical species in PTFE, N2 and Cu mixture for several proportions and pressures. We show that the nitrogen gas does not satisfy the characteristic of good dielectric leading manufacturers to modify entirely their electrical insulation set up.
