Description
Summary:The paper examined the stochasticity of the random variable electrical breakdown of electronegative gases (SF6 gas) in homogeneous, inhomogeneous, and highly inhomogeneous electric fields. These tests indirectly allowed for the assessment of the homogeneity of the insulating properties of the electronegative gas within the inter-electrode space. Tests were con- ducted at pressures ranging from 10-3 bar to 5 bar and an inter-electrode distance from 0.1 mm to 5 mm. During the test, it was established that the insulation with electronegative gas is inhomogeneous in the inter-electrode space. This inhomogeneity is explained by the high affinity of SF6 gas for forming negative ions. To prevent the occurrence of inhomogeneity in the insulation with electronegative gas, a and g radiation were applied. The increase in the number of free, potentially initial electrons contributed to homogenization of the insulation with the electronegative gas.
