Abstract

In this article the quasi-modes model is used to observe the influence, in electromagnetic transient phenomena, of considering a more accurate representation of soil, taking into account the earth conductivity and permittivity frequency dependence. For an actual 440 kV three-phase transmission line the soil behavior is represented through a unique real value of conductance and through a more accurate model, considering its electromagnetic behavior
