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.

Grounding Systems Modeling Including Soil Ionization

IEEE Transactions on Power Delivery, 2008
This paper presents a hybrid frequency-time domain methodology for the modeling of grounding systems considering the nonlinear effect of soil ionization. The method is validated by analyzing two typical grounding systems under high soil ionization effects.
