20.500.12556/DKUM-96453 Ozemljitve in izenačitve potencialov transformatorskih postaj diplomsko delo Grounding and potential equalization in transformer stations Diplomska naloga obravnava ozemljitve in izenačitve potencialov v transformatorskih postajah z vidika zagotavljanja električne varnosti in zanesljivega delovanja elektroenergetskega sistema. V teoretičnem delu so predstavljeni osnovni principi ozemljitve, vpliv specifične upornosti tal ter merilne metode za določanje ozemljitvene upornosti in upornosti galvanskih povezav. V praktičnem delu so bile izvedene meritve specifične upornosti tal, ozemljitvene upornosti in upornosti galvanskih povezav na šestih različnih tipih transformatorskih postaj. Rezultati so bili analizirani in primerjani z zahtevami veljavnih standardov. Analiza je pokazala, da na učinkovitost ozemljitve poleg lastnosti tal pomembno vplivajo tudi tip transformatorske postaje, izvedba ozemljitve in kakovost galvanskih povezav. The diploma thesis deals with grounding and potential equalization in transformer stations from the perspective of ensuring electrical safety and reliable operation of the power system. The theoretical part presents the fundamental principles of grounding, the influence of soil resistivity, and measurement methods for determining grounding resistance and the resistance of galvanic connections. The practical part includes measurements of soil resistivity, grounding resistance, and the resistance of galvanic connections across six different types of transformer substations. The results were analyzed and compared with the requirements of applicable standards. The analysis showed that, in addition to soil properties, the effectiveness of grounding is significantly influenced by the type of transformer substation, the design of the grounding, and the quality of galvanic connections.
