20.500.12556/DKUM-60721 PREHODNI POJAVI V DISTRIBUCIJSKEM TRANSFORMATORJU MOČI 250 kVA TRANSIENTS IN THE 250 kVA DISTRIBUTION TRANSFORMER V tem diplomskem delu smo se ukvarjali tako s splošno kakor tudi s konkretno obravnavo dveh značilnih prehodnih pojavov v povprečnem distribucijskem transformatorju, tj. z vklopom in s kratkim stikom. Pri obravnavi smo si pomagali s sodobnimi programskimi orodji, s katerimi smo v obliki simulacij izvajali analitično in numerično obravnavo omenjenih dveh prehodnih pojavov in njunih kombinacij, prav tako pa smo s pomočjo zmogljive merilne opreme praktično izvedli številne konkretne meritve in preskuse, s katerimi smo preverjali ujemanje rezultatov ter ugotavljali vzroke morebitnih razlik/odstopanj. In this thesis we dealt with both the general as well as specific treatment of two typical transient phenomena in the average distribution transformer, i.e. the inrush current and short circuit. During the process we used modern software tools, with which we in the form of simulations carried out analytical and numerical treatment of those two transitional phenomena and their combinations. We were also using powerful measuring equipment to practically execute a number of specific measurements and tests, to check the matching of the results and to determine the causes of any potential differences/discrepancies. distribucijski transformator prehodni pojavi vklopni tok kratki stik distribution transformer transients inrush current short circuit true true false J.
