U završnom radu opisani su utjecaji elektromagnetskog zračenja kućanskih uređaja na okolinu unutar koje se nalaze. Važno je znati da svaki električni uređaj zrači elektromagnetsku energiju a ukoliko je razina te energije previsoka može jako utjecati na zdravlje ljudi te siguran rad drugih uređaja unutar radne okoline ispitivanog uređaja. Pojava prevelikog zračenja koje bi ugrožavalo druge oko sebe se naziva elektromagnetska interferencija i to je ključna pojava koja je ispitana u radu. Naime bilo je potrebno korištenjem spektralnog analizatora i dipolne konusne antene odrediti razinu zračenja uključenog uređaja u usporedbi sa razinom zračenja isključenog uređaja. Mjerenje je izvršeno prema uputama zadanim u europskoj normi EN 55014 CISPR 14 – Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus – Part 1, u opsegu spektra nazvanom radiovalovi ( 30 MHz- 1 GHz). Dobiveni podaci su obrađeni u računalnom programu Microsoft Excel-u te je zaključeno kako ne dolazi do pojave interferencije kod odabranih uređaja, dakle možemo reći kako su odabrani uređaji elektromagnetski kompatibilni.

This final paper describes the influence of electromagnetic radiation of household appliances on the environment they operate in. It is important to know that every electrical device emits electromagnetic radiation, and if the level of that radiation is too high,it can greatly impact people’s health and a safe working environment of the device under testing. This phenomenon of excessive emission that would endanger everything around the device is called electromagnetic interference and it is the key phenomenon tested in this final paper. It was necessary to determine the emission level of the operating device and compare it with the emission level of the devicethat is switched off. This was done by using a spectrum analyser and a conical dipole antenna. Measurements were performed pursuant to guidelines specified in the European standard EN 55014 CISPR 14 – Electromagnetic compatibility – Requirements for household Sažetak 28 appliances, electric tools and similar apparatus – Part 1, within the range of the spectrum called radio waves (30 MHz-1 GHz). The data collected were processed in Microsoft Excel. It was concluded that there is no interference in selected devices; hence it can be said that selected devices are electromagnetically compatible.
