|a U radu se obrađuje kratki spoj u elektroenergetskim mrežama prema IEC 60909 standardu. Objašnjen je proračun impedancija kratkoga spoja za pojedine dijelove elektroenergetske mreže, te proračun početne, udarne i rasklopne struje kratkog spoja. Naglasak je na trofaznom i jednofaznom kratkom spoju. Kratki spoj je podjeljen na kratki spoj blizu generatora te kratki spoj daleko od generatora.
Na kraju rada nalaze se proračuni kratkog spoja jedne test mreže provedeni na tri naponske razine: 110, 10 i 0.4 kV.

|a This paper deals with short circuit faults in power grids according to the IEC 60909 standard. The short-circuit impedance calculation for individual parts of the power grid is explained, as well as the calculation of the initial, peak and breaking current of the short circuit. The emphasis is on three-phase and single-phase short-circuits. The short circuit fault is divided into a short circuit fault near the generator and a short circuit fault away from the generator.
At the end of the paper, the short-circuit calculations of one test network are calculated at three voltage levels: 110, 10 and 0.4 kV.
