Abstract
U ovom radu su prikazane teorijske osnove i fizikalna slika kratkog spoja. Kao teorijska osnova prikazane su vrste kratkog spoja, uzroci, posljedice i struje kratkog spoja. Pod fizikalnom slikom se podrazumijeva udaljenost mjesta kvara od izvora što ima veliki utjecaj na struje. Kratki spoj je pojava koja ima veliki utjecaj u radu postrojenja i zbog toga je potrebno raditi proračune struja kratkog spoja. Kod proračuna je potrebni poznavati na koji način je moguće reducirati mrežu (Theveninov teorem). Glavni zadatak ovoga rada je proračun iz kojeg se može zaključiti koji element i koliko utječe na struje. Osim toga može se vidjeti kako mrežni izvor utječe na struje kratkog spoja. Da bi se izbjegle pogreške u proračunu do kojih može doći zbog ljudske nepažnje, u radu je korišten računalni program Easy Power u kojem je nacrtana radijalna mreža sa jednim izvorom napajanja i u kojem su dobiveni rezultati simulacije koji su prikazani u prilogu.

Parallel abstract (English)
In this final thesis are described theoretical basics and physical image of short-circuit. Theoretical bases include short-circuit types, causes, consequences and short-circuit currents. Physical image means the distance from place where short circuit appeared to source and that has big influence on the currents. Short circuit has big influence on the operation on the plant and because of that is necessary to do short-circuit calculations. In calculation it is necessary to know how to reduce the network (Thevenin's theorem). The main task of this final thesis is calculation from which we can see which elemenet and how much it affects the current. Except that, we can see how source affects on the short-circuit currents. To avoid mistakes (because of human inattention), in this final is used computer program Easy Power. In this program is drawn radial network with single source and there are differents results which are shown in appendix
