This article is contribution on the digital analysis of the RLC model of the earth connector. The RLC model of the earth connector was feigned on MATLAB. These simulations were made with the horizontal earth connector and the vertical earth connector with a ground of resistivity 1000Ω.m and on the other hand with a ground of resistivity 2000Ω.m.
The results obtained by feigning on MATLAB both electrodes show that earth connectors must be buried in depths superior or equal to 6 meters. The relevance of this article, it is to help to determine the depths to which the earth connectors of the model RLC can be buried.
This paper is about grounding resistances next to the grounding systems of electric pylons and transformation stations in several localities of Ivory Coast. The data of grounding resistances got next to CIE facilitated drawing of curves and their analysis. The low resistances values from 1Ω to 2Ω of ground in some localities show that the electricity network is safe, on the other hand the high values more than 10Ω in other area show that it is necessary to plan appropriate grounding systems to protect the high voltage electricity network. To solve problem, we suggest techniques of reduction of these grounding resistances. The relevance of this paper is to contribute to the improvement of the grounding systems to protect high voltage electricity networks.
