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 ...

Soil Treatment to Reduce Grounding Resistance by Applying Low-Resistivity Material (LRM) and Chemical Ground Electrode in Different Grounding Systems Configurations

IEEE International Autumn Meeting on Power, Electronics and Computing, 2018
The effectiveness of the application of LRM is disclosed through field tests to decrease the resistance of grounding in different configurations of grounding systems.

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.
