20.500.12556/DKUM-98642 Nov pristop k izvedbi ozemljevanja nizkonapetostnih naprav, napajanih iz visokonapetostnih stikališč magistrsko delo A new approach to the implementation of grounding of low-voltage installations supplied from high-voltage substations Cilj magistrskega dela je analizirati in sistematično obravnavati pristope k izvedbi ozemljevanja nizkonapetostnih naprav, ki so napajane iz visokonapetostnih stikališč, ter določiti tehnično ustrezne rešitve z vidika varnosti in zanesljivosti. Poudarek naloge je na proučitvi vpliva zemeljskih stikov na visokonapetostni strani na razmere v nizkonapetostnem sistemu, predvsem z vidika dviga ozemljitvenega potenciala (GPR), napetosti dotika in koraka ter prenosa potenciala med VN in NN ozemljitvenimi sistemi. V ta namen bo izdelan numerični model ozemljitvenega sistema v programu XGSLab. Dobljeni rezultati bodo v magistrskem delu predstavljeni v obliki grafov in tabel. The objective of the master's thesis is to analyze and systematically examine approaches to the grounding of low-voltage installations supplied from high-voltage substations and to determine technically appropriate solutions from the perspective of safety and reliability. The thesis focuses on the analysis of the impact of high-voltage ground faults on conditions within the low-voltage system, particularly with regard to ground potential rise (GPR), touch and step voltages, and the transfer of potential between HV and LV grounding systems. For this purpose, a numerical model of the grounding system will be developed using the XGSLab software. The obtained results will be presented in the thesis in the form of graphs and tables. specifična upornost zemlje ozemljitveni sistemi električne polnilnice stikališča prenos potenciala soil resisivity grounding system EV chargers substations transferred potential true true false M.
