Harmonic grounding impedance of rods in horizontally stratified soils using ABCD-matrix approach
e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023 Grounding electrodes play a fundamental role in the operation of power systems. In this context, precise computation of grounding impedance must consider the frequency-dependence of the soil parameters and the ground organized in stratified layers of ...

Frequency Dependence of Multilayer Soil Electrical Parameters: Effects on Ground Potential Rise
International Conference on Logic Programming, 2021 The paper presents a comprehensive study on the effect of frequency dependence of multilayer soil electrical parameters (SEPs) on ground potential rise (GPR). The lightning current has a large effect on the GPR.

Characteristics of Two Ground Grid Potentials After a Triggered Lightning Stroke
IEEE Access, 2020 It has been determined that the discharge of lightning current to ground through grounding grid results in high potential at the grounding grid and other nearby grounding grids, which is very destructive.
