Short circuits calculations according to IEC 60909 and superpositions method

Cilj ovog rada je na što bolji način prikazati postupak proračuna struje. Korištenjem navedene literature objašnjeno je što bi to bio kratki spoj, koje su to značajke kratkih spojeva , te koje vrste kratkih spojeva postoje, odnosno koje su to karakteristične veličine koje se određuju pri proračunu struja kratkog spoja. U radu se nalaze opće smjernice, te proračun struje kratkog spoja IEC standardom te metodom superpozicije što zapravo i jest tema ovoga rada.The aim of this work is the best possible way to display the current calculation process. Using the above literature it is explained what would be short circuits, which are features of short circuits, and which types of short circuits exist, or that are characteristic for the size of which are determined in the calculation of the short-circuit current. In this paper are general guidelines, and the calculation of the short - circuit current IEC standards and the method of superposition what really is the topic of this work
