Three-phase fault current calculation using superposition method

U ovom radu navedene su metode analiza mreža, a detaljno je obrađena metoda superpozicije. Također, opisane su i simetrične komponente trofaznih sustava. Ukratko su opisane sve vrste kratkih spojeva, dok je tropolni kratki spoj detaljno objašnjen. Izvršen je proračun tropolnog kratkog spoja metodom superpozicije kojeg se je kasnije provjerilo i usporedilo računalnom simulacijom.In this paper, methods for circuit analysis are listed while the superposition method is described in detail. Also, symmetrical components of the three phase short circuit are described. All types of short circuits are briefly described, while the three phase short circuit is thoroughly explained. A calculation of a three phase short circuit is performed using the superposition method which was later verified and compared with a computer simulation
