Analysis of Grounding Systems Including Freely Oriented Plates of Arbitrary Shape in Multilayer Soils

This paper presents the analysis of grounding systems including freely oriented conductors and metallic plates of arbitrary shapes in horizontal multilayer soils. The analysis method yields not only the scalar potential but also the electric field and current density in the soil in the low frequency...

Description
Summary:This paper presents the analysis of grounding systems including freely oriented conductors and metallic plates of arbitrary shapes in horizontal multilayer soils. The analysis method yields not only the scalar potential but also the electric field and current density in the soil in the low frequency limit. Numerical results are provided for various configurations such as a single plate, a plate with rods, parallel plates, a box, or cylinders formed by multiple plates and are verified against available analytical methods.
