The influence of ionizing α and γ radiation on the statistics of the random variable electrical breakdown of electronegative gases
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 t...

| 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. |
