20.500.12556/DKUM-54237 ANALIZA VPLIVA PREVODNOSTI ZEMLJE IN GEOMETRIJE OZEMLJILA NA PORAZDELITEV ELEKTRIČNEGA POTENCIALA ANALYSIS OF THE IMPACT OF SOIL CONDUCTIVITY AND EARTHING GEOMETRY IN THE DISTRIBUTION OF ELECTRIC POTENTIAL Namen diplomskega dela je analiza vplivov prevodnosti zemlje in geometrije ozemljila na porazdelitev električnega potenciala. Predstavljene so različne geometrije ozemljil in različne upornosti enoplastne in dvoplastne zemlje. V nalogi je narejena primerjava med klasičnim načinom izračuna ozemljilne upornosti in načinom z metodo končnih elementov. Za različne modele geometrij ozemljila in plasti zemlje je prikazana porazdelitev potenciala, napetosti koraka in napetosti dotika. Med posameznimi primeri je narejena tudi primerjava. The purpose of this diploma paper is to analyse the impact of soil conductivity and earthing geometry on the distribution of electrical potential. Different examples of earthing geometry are presented along with examples of one layered and two layered soils. Calculations of earthing resistance are made with the classic method and compared with the finite element method calculations. Potential distribution, step voltage and touch voltage are presented for different geometries and soil conductivities which are compared between themselves. ozemljilo električni potencial ozemljilna upornost napetost koraka napetost dotika earthing system electrical potential earthing resistance step voltage touch voltage true true false N.
