Investigation of soil ionization propagation in two-layer soil samples [PDF]
2015 50th International Universities Power Engineering Conference (UPEC), 2015 High current lightning strikes into earthing systems \ud can result in ionization in the soil surrounding the earthing electrode. Most of the published studies investigating this phenomenon have assumed uniform one-layer soil, but soil ionization propagation in a multilayered soil sample has not \ud been extensively addressed.

Ionization constants of a soil fulvic acid [PDF]
Analusis, 1999 In the study of acid-base reactions the non-electrostatic models do not consider the charge over the fulvic acid (FA) molecule. In the present work we used the discrete site model which considers the acidic groups as independent sites without interactions. The effect of the electric charge is assumed negligible or constant.

Evaluating the High Frequency Behavior of the Modified Grounding Scheme in Wind Farms
Applied Sciences, 2017 Wind generators are exposed to numerous destructive forces such as lightning and are therefore vulnerable to these phenomena. To evaluate the transient behavior of a wind power plant during direct and indirect strikes, modeling of all relevant components
