Ground resistance-revisited

IEEE Transactions on Power Delivery, 1989
The nature of ground resistance is examined to explain the high impedance of faults directly to ground as contrasted to conventionally assumed low-impedance ground faults to neutral conductors or to towers with low footing resistance. High-impedance faults are shown to be inherently nonlinear due to the characteristics of soil.

Evaluation of ground resistance of a grounding grid of any

IEEE Power Engineering Review, 1991
A large number of grounding grids in substations have shapes other than a square or a rectangle, whereas the formulas and graphs for the ground resistance of a grounding grid available in the literature are applicable only to nearly square or rectangular grids.

Resistance to ground and mesh voltages of ground grids

Proceedings of the Institution of Electrical Engineers, 1979
The paper presents the results of a digital analysis of a wide set of square and rectangular grounding grids. The diagrams for grid resistances and mesh voltage factors are displayed appropriate for practical design purposes. Simple approximate formulas for both grid parameters considered are also proposed, providing a fair estimation of the parameters.

Calculation of resistances to ground

Electrical Engineering, 1936
Formulas for practical use in the calculation of the resistances from grounding conductors of variou forms to the earth are given in this paper and their use illustrated by examples. The accuracy of the formulas varies considerably, as discussed in the paper, but is sufficiently good that the methods should be helpful to those whose work involves ...

DETERMINATION OF THE MUTUAL GROUND RESISTANCE OF ADJACENT GROUNDING GRIDS

Journal of Energy - Energija, 2022
The article discusses the determination of the mutual ground resistance of two adjacent metallically connected grounding grids. For this purpose, an original analytical expression for calculating the corresponding mutual ground resistance of two adjacent grounding grids has been developed.
