Calculation of resistances to ground
Electrical Engineering, 1936Formulas 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, 2022The 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.

Prediction of Soil Resistivity and Ground Rod Resistance for Deep Ground Electrodes
IEEE Transactions on Power Apparatus and Systems, 1980A technique for the prediction of soil resistivity and ground rod resistance for deep ground electrodes has been developed. The method extrapolates limited test ground rod data to a factor of up to ten times the known depth values. The technique has been shown to accurately predict the effectiveness of installing deep ground electrodes and the ...

The value of the ground resistance is a very important factor to be considered for reliable operation of electrical appliances at home, industry and commercial buildings. The ground resistance essentially provides three important characteristics, namely (i) zero potential reference for the electrical system, (ii) low resistance path to protect ...

IEEE Transactions on Industry Applications, 1983
High-resistance grounding of electrical power systems offers many of the advantages of both solidly grounded systems and ungrounded systems, including practical suppression of transient overvoltages, practical reduction of equipment damage due to ground fault, and the ability to continue to operate a system with a ground fault present on one phase. The

Android tool to evaluate grounding resistance
2015 IEEE International Telecommunications Energy Conference (INTELEC), 2015In the absence of sources of rapidly varying field, the study of the potential distribution determined, in a linear medium, by a geometrically complex grounding may be conducted by applying the method of superposition of the effects, known as method of subareas of Maxwell.

Calculation of grounding resistance
Electric Power Systems Research, 1984Abstract This paper introduces an algorithm for the calculation of grounding resistance based on the boundary element method (or current simulation method). A series of computer results for different kinds of grounding systems is presented. On the basis of the computer results, an evaluation is made of commonly used formulas for grounding resistance ...

Reduction of a Cone-Shaped Terrain Grounding Resistance by Remote Grounding
2019 International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2019Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to have line of sight to end users. Those locations are usually very rocky and characterized by a low-conductivity soil.

Grounding System Parameters and Expression of Ground Resistance
2016In any electrical circuit network, the circuitry that provides a path between the parts of the circuit and the ground, is known as the grounding system. The grounding system is required for reliable operation of any electrical equipment including generator, transformer, power system tower, and other power system installation under fault conditions.
