How to Reduce the Soil’s Resistivity

Published by Lorenzo Mari, EE Power – Technical Articles: How to Reduce the Soil’s Resistivity, September 28, 2020. Lowering the resistance of a grounding electrode is not always enough to reduce the soil’s resistivity. Reducing the resistivity of the soil around the electrodes can help achieve adequate resistance to the ground. The elements that most affectContinue reading “How to Reduce the Soil’s Resistivity”

Electromagnetic Disturbances Propagation Along a Grounding Grid Subjected to Lightning Currents

Published by Rafael ALIPIO, Renan SEGANTINI, Federal Centre of Technological Education of Minas Gerais Abstract. This paper assesses the transient distribution of potentials along a grounding grid subjected to currents representative of first and subsequent strokes. It is shown that the transient non-uniform distribution of potential along the grounding system may lead to the flowContinue reading “Electromagnetic Disturbances Propagation Along a Grounding Grid Subjected to Lightning Currents”
