Abstract	Kratki spoj je kvar čija je pojava prouzročena nizom okolnosti. Posljedica je protjecanje struje kratkog spoja. Svi dijelovi mreže su izloženi povećanom naprezanju. Povećanje potrošnje električne energije zahtjeva bolju izgrađenost mreže. Za zaštitu od struja kratkog spoja u niskonaponskim mrežama upotrebljavaju se osigurači i zaštitni automatski prekidači. Za zaštitu transformatora na primarnoj strani upotrebljavaju se visokonaponski osigurači i zaštitni releji. Zadatak svih zaštitnih uređaja je da na brzo isključe struju kratkog spoja. Dodatni zahtjev je da uvijek isključuje onaj zaštitni uređaj koji je najbliže mjestu kvara. S tim se ispunjava vrlo zahtjevan uvjet za selektivnost. Poznavanje karakteristika niskonaponske mreže važno je za pravilno određivanje struje kvara. Te struje ovisne su o izvedbi i dužini vodiča razdjelne mreže. U radu je opisana analiza struje kratkog spoja u niskonaponskoj mreži. Pravilni izbor zaštite od struje kratkog spoja uvjet je za održavanje sigurnosti i stabilnosti mreže i pouzdano selektivno djelovanje zaštitnih uređaja.
Abstract (english)	Short circuit is a fault which appearance is caused by a variety of circumstances. It's after effect is a short circuit current flow. All parts of power network are exposed to additional stress. Power consumption increment demands better network construction. Fuses and automatic protective circuit-breakers are used for short circuit current protection in low voltage networks, while high voltage fuses and protective relays are used for transformer protection on the primary side. Every protective device task is turning off short circuit current as soon as possible. Additional demand is that always the closest device to fault should operate. This is important for selectivity. Knowing low voltage network characteristics is important for correct determination of fault current. This current depends on construction and length of distributed network conductors. Short circuit current analysis in low voltage networks is described in these papers. Proper selection of short circuit protection is essential for maintaining the safety and stability of network and for reliable selective operation of protective devices.
