Computation of ground potential rise and grounding impedance of simple arrangement of electrodes buried in frequency-dependent stratified soil
(2021-09-01)
Grounding electrodes are used to provide a low-impedance dissipation path for the excess lightning or fault currents. Several studies have been dedicated to the computation of the grounding impedance of different electrode ...

Computation of Surge Voltage in Transmission Tower Located above Frequency-Dependent Soil
(2021-01-01)
The purpose of this paper is to investigate the influence of frequency-dependent soils with variable soil content on the transient voltages at transmission towers. First, a comparative analysis between the impedance of ...
Lightning Current on the Frequency-Dependent Lumped Parameter Model Representing Short Transmission Lines
(2021-01-01)
The purpose of this paper is to investigate the performance of the Frequency-Dependent Lumped Parameter Model (FD-LPM) to adequately represent two distinct overhead transmission lines (OHTLs) subjected to different lightning ...
A New Approach to Compute Grounding Impedance of Rods in a Frequency Dependent Multi-layer Soil
(Ieee, 2020-01-01)
Long cylindrical rods are commonly employed to grounding system in transmission lines and they can be buried in stratified soils. In this condition, the grounding impedance is significantly modified by the presence of ...
