Abstract	Zadatak završnog rada je ispitati elektromagnetsko zračenje odabranih svakodnevnih kućanskih uređaja. Elektromagnetsko zračenje nastaje kao kombinacija električnog i magnetskog zračenja te njihovog zajedničkog širenja u obliku vala. Svi uređaji koji za svoj rad koriste električnu energiju stvaraju u svojoj okolini elektromagnetsko polje, a ovisno o jačini elektromagnetskog polja može doći do elektromagnetske interferencije (EMI) te do negativnih posljedica za ljudsko zdravlje. Kako bi svi uređaji bili sigurni za svoju okolinu, postavljaju se razne norme koje određuju granice dopuštenog elektromagnetskog zračenja uređaja. Jedna od takvih normi je HRN EN 55014:1 koja postavlja granice EM zračenja u frekvencijskom spektru od 30 MHz do 1000 MHz te propisane parametre mjerenja po kojima je mjerenje izvršeno. Za mjerenje zračenja uređaja koristi se spektralni analizator i dipolna konusna antena. Svi su uređaji mjereni u svim svojim kombinacijama rada za sva tri položaja antene (x, y, z – osi). Kako bi se osigurali što precizniji rezultati mjerenja te eliminirale ostale grupe signala u zadanom frekvencijskom spektru, uspoređene su vrijednosti uključenog uređaja s vrijednostima isključenog uređaja. Analizom konačnih rezultata zaključeno je da su svi testirani uređaji u dopuštenim granicama norme HRN EN 55014:1 te su sigurni za normalan rad.
Abstract (english)	The aim of the final paper is to examine the electromagnetic radiation of selected everyday household appliances. Electromagnetic radiation is created as a combination of electric and magnetic radiation and their joint propagation in the form of a wave. All devices that use electricity for their work create an electromagnetic field in their environment, and depending on the strength of the electromagnetic field, electromagnetic interference (EMI) can occur and have negative effects on human health. To keep all devices safe for their surroundings, various standards are set that set limits to the permitted electromagnetic radiation of the device. One such standard is HRN EN 55014: 1, which sets the limits of EM radiation in the frequency spectrum from 30 MHz to 1000 MHz and the prescribed measurement parameters by which the measurement was performed. A spectral analyzer and a dipole cone antenna are used to measure the radiation of the device. All devices were measured in all their combinations of operation for 26 all three antenna positions (x, y, z - axes). In order to ensure accurate measurement results and eliminate other signal groups in the given frequency spectrum, the values of the included device are compared with those of the excluded device. The analysis of the final results concluded that all tested devices are within the limits of HRN EN 55014: 1 and are safe for normal operation.
