Calculation of the impulse impedance of the grounding system

Zadatak diplomskog rada bio je provesti proračun impulsne impedancije preko modela uzemljivača kojeg je bilo potrebno izraditi na računalu. Cjelokupan opis zadatka kao i uvodna riječ o uzemljivačima i sustavu uzemljenja obrađena je u prvom poglavlju. U drugom poglavlju zastupljen je pregled literature koji je korišten kao teorijska podloga u diplomskom radu. Treće poglavlje govori koje vrste uzemljenja postoje. Četvrto i peto poglavlje opisuje vrste tla i njihov utjecaj na uzemljenje, te se govori o naponima koraka i dodira. U šestom poglavlju govori se u vrstama uzemljivača i njihovom obliku izvedbe. U sedmom poglavlju govori se o impulsnim karakteristikama uzemljivača i time završava teoretski dio i nakon toga se prelazi na simulaciju i analizu modela koji je izrađen računalnim programom XGSLab.The task of the master thesis was to perform the calculation of the pulse impedance through a grounding model which needed to be made on the computer. The complete description of the task, as well as the introductory word about the grounding conductors and the grounding system, is dealt with in the first chapter. Literature review, which has been used as theoretical background in the thesis, is presented in the second chapter. The third chapter discusses types of grounding. Chapters four and five describe types of soil and its impact on grounding, and discuss step and touch voltage. Chapter six discusses types of grounding conductors and their form of execution. Chapter seven discusses impulse characteristics of the grounding conductor and thus completes theoretical part, proceeding to stimulation and analysis of a model created by computer program XGSLab
