Abstract
By using X-ray film imaging technology, a phenomenon of discontinuous ionization was observed in the inhomogeneous soil around the grounding electrode on which a surge voltage was applied. A simplified two-phase solid-gas model was built to study the electric field distribution in the soil to explain the discontinuous ionization phenomenon. Analysis showed the differences of the dielectric properties, the shapes and sizes of soil particles can cause discontinuous ionization in the soil.
