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.

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

Thermodynamic studies for adsorption of ionizable pharmaceuticals onto soil

Chemosphere, 2014
Although pharmaceutical compounds (PCs) are being used more and more widely, and studies have been carried out to assess their presence in the environment, knowledge of their fate and behavior, especially under different environmental conditions, is still limited.

Ionizing radiation attracts soil fungi

Mycological Research, 2004
During the last 15 years, about 2000 strains of 200 species of 98 genera of fungi have been isolated from around the Chernobyl Atomic Energy Station. Many of these microfungi are capable of growing into and decomposing 'hot particles'; carbon based radioactive graphite from the reactor and there are suggestions that some fungi actively direct their ...

Influence of ionized saline water on soil water and salt transport in saline soils

Irrigation and Drainage, 2022
AbstractThe utilization of saline water plays an important role in agricultural production in saline areas to overcome freshwater shortages. Ionized saline water might alleviate the adverse effects of salinity on soil and plants. In this study, field experiments were conducted to study the effect of ionized saline water on the soil water content and ...

EFFECT OF IONIZING RADIATION ON SOIL MICROORGANISMS

Soil Science, 1961
The effects of neutron and gamma radiation on soil bacteria, actinomycetes, and fungi, and on nitrifying bacteria, nitrogen fixation, and CO/ sub 2/ evolution were studied. Soil samples from alfalfa and ammonia-treated soils at two moisture levels were exposed at a dosage of 4.13 x 10/sup 12/ neutrons per cm/sup 2/ and a mean gamma dosage of 3.4 x 10 ...

Laser Two-Photon Ionization of Pyrene on Contaminated Soils

Analytical Chemistry, 1996
We report a first attempt to use the laser multiphoton ionization method for analysis of trace aromatic compounds on the surface of environmental (soils) and artificial (silica) samples. The measurement setup is composed of a N(2) pulsed laser and a fast conductivity detection system.
