Impulse Efficiency of Ground Electrodes [PDF]
IEEE Transactions on Power Delivery, 2009 The lightning current waveform has a major influence on the dynamic performance of ground electrodes. While high lightning current intensity improves the dynamic grounding performance due to ionization of the soil, very fast fronted pulses might worsen the performance in case of inductive behavior.

Effect of Impulse Polarity on a New Grounding Device with Spike Rods (GDSR)
Energies, 2020 The characterizations of grounding systems subjected to high impulse conditions are known to be dependent on the polarity, current to peak time and discharge time, as well as the electrical properties of the soil, and the grounding electrodes themselves.
