This paper presents experimental results of three electrode's configurations, 1-rod, 2-rod and 3-rod electrodes. A high impulse current generator is employed to inject different magnitudes of current into these rod electrodes. The effect of increasing number of rod electrodes on the voltage and current waveforms, time to peak current, discharge time and impulse resistance values is analyzed. From the results analysis, it was found that the larger the size of rod electrodes, the lower the reduction of impulse resistance, R impulse from its steady state, RDC . Inductive effect was also found to be significant for higher number rod electrodes, particularly at lower current magnitudes.
