| Abstract | U radu je teorijski objašnjeno značenje i važnost uzemljivača i uzemljivačkih sustava, kao i njihova podjela. Također objašnjena je specifična otpornost tla, načini na koji se ona može mjeriti te su navedeni prijedlozi za točnija mjerenja. Odrađena su 4 različita mjerenja otpornosti tla, 3 lokacije u zemlji imaju ukopanu metalnu konstrukciju koja je utjecala na rezultate mjerenja otpornosti tla, dok četvrta nema te služi za usporedbu s ostalim rezultatima. Mjerenja su odrađena koristeći Wenner-ovu metodu mjerenja specifične otpornosti tla, uz pomoć mjernog instrumenta UNILAP 100 XE. Provedena je analiza dobivenih rezultata te je prikazan utjecaj ukopanih metalnih konstrukcija na mjerenje specifične otpornosti tla. Dobiveni rezultati mjerenja korišteni su kako bi se dobila analiza tla putem programa CYMGrd. Putem navedenog programa dobivene su jednoslojne i dvoslojne analize tla te grafički prikaz, odnosno krivulje specifične otpornosti tla za svako mjerenje. |

| Parallel abstract (English) | In this paper the meaning and importance of grounding and grounding systems, as well as their classification are theoretically explained.Also specific soil resistivity and the ways in which it can be measured are explained. And proposals for more accurate measurements were made. Four different soil measurements were made, 3 of them were on the location where soil has burried metal services that will take effect on results of soil resistivity measurement, while the fourth measurement doesn't have burried metal services and the result of this measurement is used in order to compare with other results. Measurements are made by Wenner's soil resistivity measuring method using UNILAP 100 XE measuring instrument. Analysis of the measurement results was preformed and the influence of burried metal services was shown. Results of measurement were used to make soil analysis using software CYMGrd. Through this program one-layer and two-layer soil analysis were made. CYMGrd also gave graphical analysis by drawing curves of specific ground resistivity for each of measurements |
