Abstract
Tranzijentno ponašanje uzemljenja transformatorske stanice prilikom udara groma istražuje se primjenom teorije polja. Prilikom udara groma u trafostanicu generiraju se velike struje u uzemljivačkom sustavu i disipiraju se u zemlju. Elektromagnetska polja uzrokovana takvim velikim strujama mogu uzrokovati štetu na opremi i mogu biti opasna za osoblje u transformatorskoj stanici. Teoriju polja treba koristiti za dobivanje točnog prikaza tranzijentnog ponašanja procesa udara munje u sustava uzemljenja trafostanice. U ovom radu modeliran je sustav uzemljenja trafostanice podvrgnut udaru munje u frekvencijskoj domeni. Numerički rezultati su prikazani u grafičkom obliku.

The transient behaviour of a transformer station grounding system subjected to a lightning strike is investigated using a field theory approach. When lightning strikes and transformer station, large currents generatd by stroke flow in the grounding system and dissipate in the soil, The electromagnetic fields generated by such high currents may cause damage to equipment and may be dangerous to the personnel in transformer station. A field theory method should be used to obtain an accurate representation of the transient behaviour of the lightning process in the transformer station grounding system. In this paper, the frequency domain response of a transformer station grounding system subjected to a lightning strike have been modelled. numerical results are presented graphical form.
