Protection of medium voltage distribution networks

U diplomskom radu sam opisao vrste kratkih spojeva koje mogu nastupiti. Naveo sam načine zaštite srednjenaponskih postrojenja i koji je zadatak relejne zaštite ako nastupi poremećaj ili kvar. Detaljno sam opisao kako se štite pojedini elementi postrojenja. Korišteni relej za zaštitu je KONPRO RIUX 621. Relej proizvodi tvrtka Končar, relej ima široki spektar zaštitnih funkcija.In graduate thesis I have described the types of short joints that can occur. I have outlined the ways of protecting medium-voltage installations and which is the task of relay protection if a disorder or malfunction occurs. I have described in detail how to protect individual elements of the plant. The used relay for protection is KONPRO RIUX 621. Relay is manufactured by Koncar, the relay has a wide range of protective functions
