In cases where the grounding system is buried in soils characterized by poor contact with the electrodes (e.g., karst and sandy terrains), the contact resistance frequently represents a dominant component of the total grounding resistance. In such cases, estimation of the grounding resistance by conventional formulas given in the literature is useless,

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, 1991A 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, 1979The 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.

Directional ground fault indicator for high-resistance grounded systems
IEEE Technical Conference Industrial and Commerical Power Systems, 2002Locating ground faults is a difficult and challenging problem for low-voltage power systems that are ungrounded or have high-impedance grounding. Recent work in pilot signals has renewed efforts in developing fault location methodologies. This paper presents a method for directional ground-fault indication that utilizes the fundamental frequency ...
