An Estimator of the Resistance of Large Grounding Electrodes from Its Geometric Characterization
Applied Sciences, 2020 An estimator of the grounding resistance of large extension electrodes from the total length and geometric properties of the electrode is proposed in this work. The approximation is valid for electrodes buried in a soil that can be assumed as homogeneous

Research on Discharging Current Distribution of Grounding Electrodes [PDF]
IEEE Access, 2019 Grounding electrodes with good current discharging performance can ensure the reliability of power system security. Discharging current is not only the reason for accelerating the corrosion, but also the key indicator of the grounding electrodes' grounding performance, which directly affects the grounding resistance, step voltage, ground potential ...

Grounding Resistance and Grounding Impedance of Horizontal Bundled Conductor Grounding Electrodes.
IEEJ Transactions on Power and Energy, 2003 It is well known that increasing conductor radius of grounding electrode results in decreasing grounding resistance, but the decrease extent is very little compared with the increase extent. However, when bundled conductors are used for grounding electrode, lower grounding resistance is expected to be obtained. Thus the bundled conductors of horizontal
