Abstract:V prvem delu diplomskega dela so opisani različni načini tretiranja srednje napetostne nevtralne točke energetskega transformatorja in teoretično obnašanje SN-omrežij ob nastopu enopolnega zemeljskega stika. Predstavljene so zgodovina tretiranja nevtralne točke in možne okvare v energetskem sistemu. Predstavljeni so možni načini odkrivanja okvarjenega izvoda na podlagi opazovanja ključnih veličin. V drugem delu so bili analizirani primeri zemeljskih stikov na omrežjih podjetja Elektro Maribor d. d. z različnimi načini ozemljitve nevtralne točke.
Keywords:tretiranje nevtralne točke, enopolni zemeljski stik, izolirana nevtralna točka, indirektno ozemljena nevtralna točka, resonančno ozemljena nevtralna točka

Title:Operation of distribution power grid with different neutral point grounding system
Abstract:In the first part of this thesis, operation of distribution power grid with different neutral point grounding system and theoretical behaviour of medium-voltage level system in the event fan earth fault are described. The history of treatment of the neutral point and possible malfunctions in the energy system is presented. Possible ways of detecting a defective line based on the observation of key quantities are also presented. In the second part, examples of earth contacts with different methods of grounding of the neutral point on the Elektro Maribor power grid were analyzed.
Keywords:neutral point grounding, earth fault, isolated neutral point, resistance earthed neutral point, resonant earthed neutral point
