On the Concept of Grounding Impedance of Multipoint Grounding Systems

IEEE Transactions on Electromagnetic Compatibility, 2014
An N-port equivalent circuit approach is adopted to model a multipoint grounding system, N being the number of injection points. A methodology is proposed to determine the parameters of the N-port equivalent circuit from either numerical simulations or experimental measurements.

Hybrid grounding of electrical systems

2016 Petroleum and Chemical Industry Technical Conference (PCIC), 2016
This paper will discuss the many different ways to ground medium voltage generators. Single source as well as multiple source units, either unit connected or bus connected, will be shown with preferred grounding schemes.

Grounding System Parameters and Expression of Ground Resistance

2016
In 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.

Grounding systems research: re-establishing grounded theory

Proceedings of the 35th Annual Hawaii International Conference on System Sciences, 2003
In the field of information systems (IS) there has been a growing trend away from a technical view of systems (with the system literally seen primarily in terms of the physical devices), to one that seeks to account for nontangible aspects such as cognition, culture, motivation and so on.

Ground-3D: A FEM CAD/CAE System for Ground Systems Analysis

Digest of the Fifth Biennial IEEE Conference on Electromagnetic Field Computation, 2005
A complete modelling of a grounding system made by ground meshes, connected or not in multilayer soil is presented. A 3D approach is used to model rods or wire conductors, grave layers and conductor plates that are commonly found in grounding systems.

Analysis of Grounding Systems

IEEE Transactions on Power Apparatus and Systems, 1981
A general methodology for the analysis of electrical grounding systems is presented. Earth is represented as a two layer semiinfinite region. An equivalent circuit model of the earth embedded electrodes and conductive soil is developed via numerical lution of Laplace equations.

Corrosion and Grounding Systems

IEEE Transactions on Industry Applications, 1977
Corrosion that occurs in the presence of dissimilar metals in the same electrolyte, or same metal in different electrolytes, or in different concentrations of the same electrolyte, has caused numerous problems in operating electric systems. This corrosion is the result of a potential difference existing between two surfaces which forces an electric ...

Grounding principles and practice IV — System grounding

Electrical Engineering, 1945
Grounding of transmission and distribution systems is considered in this article, the fourth of five based on a series of lectures on the subject which was sponsored by the power and industrial group of the AIEE New York Section during the 1943–44 season.

Whitelisting ground systems

SpaceOps 2012 Conference, 2012
Ground systems have a very specific function, defined at design phase, and are not used for anything else. Hence, the processes, libraries, files, network connections and other resources used are clearly specified and stable unless an approved change takes place.
