Lightning Impulse Performances of Grounding Devices Covered With Low-Resistivity Materials
IEEE Transactions on Power Delivery, 2006The low-resistivity material (LRM) is widely used to decrease the power-frequency grounding resistances of grounding devices for transmission lines in the regions with high soil resistivity. The study about the influence of the LRM on impulse performances of grounding devices cannot be found in literature.

Experimental Investigation of Impulse Resistance of Different Type Grounding Electrodes
2020 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon), 2020When spreading large pulsed currents in the soil, the electrical properties of the soil, as well as the characteristics of grounding, may differ significantly from the values obtained when spreading a weak stationary current. This is due to the ionization of the soil near the electrode and the formation of spark channels, which leads to a noticeable ...
