Understanding of Grounding Systems' Performance with Equivalent Circuit Model

It has been known that under high impulse conditions, a non-linearity in some practical grounding electrodes, subjected to fast surges was observed. Inductive component can also be significant in grounding electrodes subjected to high impulse conditions, due to the steep fronted of fast transients. This paper presents the relation of the inductance, capacitance, linear and non-linear resistive components when the grounding systems are subjected to fast impulse conditions.
