نبذة مختصرة : Na početku završnog rada objašnjeni su teorijski pojmovi vezani za atmosfersko tlo te utjecaji koji utječu na njega. Opisane su vrste i modeli tla za proračun uzemljenja te su navedene i definirane različite metode za mjerenje specifičnog otpora tla, metoda koja je korištena za ovaj završni je Wenner-ova metoda mjerenja specifičnog tla. U praktičnom dijelu korištene su četiri sonde gdje su vanjske sonde služile kao struje, a unutarnje sonde kao napon. Korišten je uređaj Metrel MI 3123 pomoću kojeg su dobiveni rezultati unešeni u program CYMGrd te su dobiveni rezultati za gornji i donji sloj tla. Na kraju je urađena usporedba odnosa količina padaline i otpornosti tla te odnos temperature i otpornosti tla kako bi se prikazala promjena otpornosti tla u odnosu na količinu padalina i porasta temperature ; The final thesis begins by introducing and explaining the theoretical concepts related to atmospheric soil, and the things that affect it. The types and models of soil used to calculate grounding are described. Additionally, various methods, for measuring specific soil resistance, are described and defined. The method used in this paper is Wenner-Test, for measuring soil resistivity. In the practical part, four probes were used, in which the external probes were used for current, and the internal ones for voltage. Metrel MI 3123, was used to acquire data which was then submitted into the CYMGrd program, after which results were obtained for the top and bottom part of the soil. Consequently, a comparison was made between the amount of rainfall and soil resistance, and also between temperature and soil resistance. This was done to show the change in soil resistance with respect to rainfall and temperature rise.
