20.500.12556/DKUM-67059 Analiza izgub v masivnem in pramenastem vodniku Analysis of losses in massive and litz wire Magistrsko delo obravnava izračunavanje električnih izgub v pramenastem in masivnem vodniku na podlagi harmoničnega izračuna elektromagnetnega polja pri frekvenci toka 1kHz , in pramenov vodnika dolžine 500mm ter njihove vzporedne ali ovite gradnje. Računalniško analizo smo izvedli s programom Opera, ki temelji na metodi končnih elementov. S teoretično obravnavo električnega polja v električno prevodnih materialih smo določili modele vodnika. Fizično smo izdelali vodnike in jim pomerili električne izgube. In those thesis are presented the calculation of electrical losses in massive and litz conductor depending on the harmonic electrical field at frequency 1kHz of electrical current as well as with conductor size of 500mm and parallel or twisted construction. Computer processing was performed with the program Opera, used to calculate the electrical losses with the finite element method. With the theoretical study of the electric field in electrically conductive material, we defined wire models. Conductors were also handmade. We measured them for electrical losses.
