摘要：

This work aims at proposing a methodology to perform an experimental evaluation of energized grounding grid systems, subjected to current impulses. By using an impulse generator (80 kJ/100 kV) impulses were generated 8/20 mu s waveforms that were injected into the soil through a copper coated steel electrode. The applied voltage signal and the propagated signal in the soil were acquired by using a digital oscilloscope. The transient impedance and impulse coefficient were used as parameters to verify the grounding grid system performance.
