Measurement of lightning impulse and AC breakdown voltages are carried out with different N2/O2 gas mixtures within a real Schneider Electric busbar tank for different inter-electrode distances and gas pressures. The electrodes are made of spheres having 2 cm and 15 cm in diameters. The objective is to yield more data at different field factors for deep analysis to determine the mixture with greater breakdown characteristics for gas part application in the hybrid insulation systems of SF6–free GIS. As an achievement, it is observed that the mixture with 10% O2 presents the best compromise regardless of the gas pressure, electrode configuration, and electric field inhomogeneity.
