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.

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 ...

Grounding for surge-protective devices ground resistance versus ground impedance
2006 IEEE Power Engineering Society General Meeting, 2006The aim of this paper is to address the often loosely used terms of impedance and resistance as related to grounding, and to educate the reader as to the significant difference between these two terms when contemplating the behavior of grounding systems impressed with transient impulse currents.

Resistance of grounding systems
Electrical Engineering, 1955ANALYTICAL expressions for the resistance to infinite ground are found in the technical literature for simple shapes of ground electrodes and wires.1 The present digest aims to establish generally applicable relations for the resistance of more complex configurations such as grids and rodbeds.

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.

Equipotentiality and grounding Derivation of grounding resistance for equipment
2014 IEEE Symposium on Product Compliance Engineering (ISPCE), 2014Equipotentiality is one means of preventing electric shock. Grounding is a specific kind of equipotentiality. For most power distribution systems, the resistance of the grounding circuit in an electrical product is critical to establishing equipotentiality. This paper explains equipotentiality and how it provides protection against electric shock. This

The measurement of impulse grounding resistance and inductance of grounding network
Proceedings of EMPD '98. 1998 International Conference on Energy Management and Power Delivery (Cat. No.98EX137), 2002It is well known that accurate measurement of grounding resistance and inductance under impulse voltage is of great importance for safe operation of electrical and electronic equipment. It is the behavior of grounding objects under impulse voltage instead under DC voltage that determine the safe operation of equipment.

Notes on Resistance of Gas-Pipe Grounds
Transactions of the American Institute of Electrical Engineers, 1907Earth connections in electric circuits are frequently made by driving a gas pipe into the ground. Such grounds are of fairly high resistance, and therefore not permissible where a low resistance ground is required. Their great simplicity and cheapness makes them desirable, where very low ground resistance is not necessary, as for discharging static ...
