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.
