Methodologies for determination of soil ionization gradient

Journal of Electrostatics, 2012
In this paper the results of the research being carried out on the impulse characteristics of soils and more specifically the ionization voltage gradient are presented. The determination of the soil ionization voltage and the respective gradient using a universally accepted method is yet to be established. Aiming at meeting this need, the present paper

Spatially discontinuous ionization phenomenon in inhomogeneous soil

Science China Technological Sciences, 2010
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.

An improved model for soil ionization around grounding system and its application to stratified soil

Journal of Electrostatics, 2004
An improved model for taking into account the effect of the soil ionization around grounding system under lightning strike is proposed in this paper. In this model, the soil ionization region is assumed to retain 7% of its pre-ionization resistivity, which is consistent with the experimental results on soil ionization found in literature (Trans.

Comparison of equivalent circuit models for the simulation of soil ionization

Electric Power Systems Research, 2014
Abstract The main characteristic of the transient behaviour of a grounding system is the decrease of the grounding impedance, due to soil ionization phenomena that take place, when the density of the injected current exceeds a critical value. In this paper three circuit models proposed by researchers have been implemented using the ATP/EMTP programme
