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 ...
Computing transient voltages on grounding grids buried in homogeneous and stratified soils
(2020-09-28)
Grounding grids (GGs) are essential to guarantee protection to personnel and equipment in the electrical substation. In this context, GGs provide low impedance path to high currents during faults or lightning strikes to ...
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 ...
