KANASHIRO, Arnaldo G  e  BEZERRA, Sergio R. C. Grounding Systems using Concrete Encased Conductors and Electrodes. Inf. tecnol. [online]. 2012, vol.23, n.3, pp. 129-136. ISSN 0718-0764.  doi: 10.4067/S0718-07642012000300016.

This work presents the results of computational simulations considering the use of concrete encased conductors and electrodes in grounding systems. The software tool Current Distribution, Electromagnetic Fields, Grounding and Soil Structure Analysis (CDEGS) was used for determining ground grid resistances. Typical values of soil resistivity and measured ground resistances were taken into account in this work to then compare them with the results obtained in the computational simulations. The results showed that the ground resistances considering concrete encased conductors and electrodes were lower than the values obtained with conventional grounding systems. The comparison between results of the computational simulations and measured values showed reasonable agreement.
