Performance evaluation of a new grounding system

This paper analyzes the performance of grounding triangular meshes, constructed with metal grounding rods coated with concrete, and metal rods coated with concrete doped bentonita compared to the mesh constructed with conventional rods (without concrete lining). The behavior of the grounding resistance of the mesh, the supportability of the concrete structure to the current impulses, the behavior of the signals of the voltages and currents caused by impulses injected into the soil, and also the impulse impedance grounding were assessed. The results were satisfactory regarding the resistance of the rods and the supportability of the concreted grounding rods to the application of impulses. Innovative results were obtained regarding impulse impedance.
