Impedance nature of long horizontal grounding electrode employing TLM
2018 International Conference on Electrical Sciences and …, 2018•ieeexplore.ieee.org
This investigation is devoted to analyse the impedance behaviour of long horizontal
grounding electrodes as function of frequency for several soil resistivity values. The real and
imaginary parts of grounding impedance have been analysed in order to characterize its
nature at several points along the electrode. We show that the impedance increase reflects
its inductive behaviour. This impedance increases with the grounding electrode length. For
high soil resistivities, resonant peaks appear. They are attenuated with the electrode length …
