Space charge and soil ionization: an electro-kinetic approach
IEEE Transactions on Dielectrics and Electrical Insulation, 2011 This paper proposes an electro-kinetic model of soil ionization for concentrated electrodes submitted to impulse currents. This approach allows a better understanding of the dynamic response of earth rods. Since current density attains a sufficient value around the electrode, ionization appears in the soil and produces a transient reduction of the ...
