Breakdown mechanisms differ in solids, liquids, and gases. Breakdown is influenced by electrode material, sharp curvature of conductor material (resulting in locally intensified electric fields), the size of the gap between the electrodes, and the density of the material in the gap.

WebApr 11, 2013 · When the local electric field exceeds the breakdown threshold of a gas, the neutral gas molecules start to become ionized by impact of electrons with energies above 12 eV. While the ionization density grows, charged particles move in the electric field and form space charge regions that modify the field. WebGaseous breakdown is a threshold process whereby a nom-inally insulating gas transitions into a conductor under the influence of an electric (or magnetic) field. Since the electrical conductivity of most gases is extremely poor (e.g. ∼ 10−15 S m −1 for ambient air), the breakdown process
