Abstract: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.

Title:A new approach to the implementation of grounding of low-voltage installations supplied from high-voltage substations
Abstract: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.
Keywords:soil resisivity, grounding system, EV chargers, substations, transferred potential
