Abstract
Pojava atmosferskog pražnjenja u sustav unosi visoke frekvencije na kojima DC model uzemljenja više nije točan. Osim pojave impedancije u sustavu, odziv na frekvenciju popraćen je i promjenama u ponašanju uzemljivačkog vodiča te ponašanju tla. Kod tla to su promjena parametara tla s frekvencijom i ionizacija tla, a kod vodiča skin efekt, propagacijski efekti i struja pomaka. Napravljen je model u ANSYS HFSS programu na temelju članka čiji su rezultati poslužili za validaciju te je proučen utjecaj frekvencije na ponašanje jednostavne uzemljivačke šipke. Također izvršene su simulacije o utjecaju različitih parametara tla i dimenzija šipke na ponašanje impedancije sustava.
Abstract (english)
The appearance of atmospheric discharge brings high frequencies into the system where the DC grounding model is no longer accurate. In addition to the appearance of impedance in the system, the frequency response is also connected with changes in the behaviour of the grounding conductor and the behaviour of the soil. In the case of soil, these are the change of soil parameters with frequency and soil ionization, and in the case of conductors there are skin effect, propagation effects and displacement current. A model was created in the ANSYS HFSS program based on an article whose results were used for validation. The influence of frequency on the behaviour of a simple grounding rod was studied. Simulations were also performed on the influence of different soil parameters and rod dimensions on the behaviour of the system impedance.
