Abstract
U ovom radu opisane su vrste kratkih spojeva i metode proračuna. Predstavljene su karakteristike i funkcije numeričkih releja. Opisano je djelovanje nadstrujne zaštite i usmjerene nadstrujne zaštite. TakoĎer je opisana KOPRO RFX serija numeričkih releja. Konačno, analizirani su kratki spojevi i izvedena je koordinacija nadstrujne zaštite na rasklopištu RS Slavonija DI (10 kV). Rasklopište RS Slavonija DI (10 kV) je dvostrano napajano (iz transformatorske stanice Brod 2 i kogeneracijskog postrojenja). Stoga je potrebna analiza tokova snaga pri kratkom spoju za oba doprinosa strujama kratkog spoja. Releje treba parametrirati tako da za kratki spoj na svakoj sabirnici postoji primarna i rezervna zaštita kako bi se osigurala pouzdanost sustava zaštite.

Parallel abstract (English)
In this paper different types of short-circuits and methods of calculation are described. Numerical reley characteristics and functions are introduced. Operation of overcurrent protection and directional overcurrent protection is described. This paper also contains description of KONPRO RFX numerical reley series. Finally, short-circuit analysis and overcurrent protection coordination of switchyard RS Slavonija DI (10 kV) was conducted. Switchyard RS Slavonija DI is powered bidirectionally (from substation Brod 2 and cogeneration plant). Consequently, analysis of power flow during short-circuit for both direction is needed. Releys have to be set so that for every fault location there is primary and reserve protection. In that way reliability of whole protection system is ensured.
