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 ...

Ground Potential Rise and Transient Response of the Grounding Grid Based on the Triggered Lightning
应用气象学报, 2020 It is extremely dangerous of ground grid potentials which significantly rise when the lightning currents are flowing through the grid. A statistical analysis on 39 return-strokes, 10 M-components and the ground potential rise (GPR) caused by them based ...

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.

Structure of an Ancient Egyptian Tomb Inferred from Ground-Penetrating Radar Imaging of Deflected Overburden Horizons [PDF]
, 2015 Geophysical data acquisitions in most archaeological campaigns aim to image the target structure directly. The presence of a target, however, may be inferred from its interaction with surrounding layers, if its relationship with those layers can be ...
