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

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 ...

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.

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 ...

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 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.

A Practical Approach for Determining the Ground Resistance of Grounding Grids
IEEE Transactions on Power Delivery, 2006This paper starts from the premise that ground resistance is independent of earth-fault current and presents a new method for calculating the ground resistance of grounding grids using the finite-element method. The results obtained using the method proposed are compared with results measured experimentally and results published by other authors.

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

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 ...
