Comprehensive Modeling of Transient Analysis of Grounding System under Lightning Surges [PDF]
مجله مدل سازی در مهندسی, 2019 During lightning discharge, the transient performance of grounding system is influenced by the time-dependent nonlinear behavior related to soil ionization and frequency dependence of soil electrical parameters related to high-frequency spectrum of ...

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.
