Abstract
U prvom poglavlju opisuju se osnovne teorijske postavke elektromagnetizma u kontekstu zračenja na ekstremno niskim frekvencijama u elektroenergetskom sustavu (50 Hz) gdje magnetsko i električno polja nisu međusobno spregnuti. U drugom poglavlju se potom navode osnovni mehanizmi sprezanja vremenski promjenjivih elektromagnetskih polja i bioloških tijela te kakvi su njihovi utjecaji na ljudsko tijelo. Navode se biološki učinci niskofrekventnih polja te mjesta interakcije i frekvencije najveće osjetljivosti za različite učinke na ljudskom tijelu. Na kraju su navedene referentne razine izloženosti promjenjivim električnim i magnetskim poljima. U trećem poglavlju navode se metode mjerenja magnetskih polja – fluxgate, fluksmetar, NMR, ESR te metoda mjerenja električnih polja (kapacitivna metoda). U zadnjem poglavlju se govori osnovno o NN asinkronim elektromotorima te o njihovim načinima pokretanja. Zatim su prikazani rezultati mjerenja koji su pokazali da zračenje asinkronog motora u normalnom radu nema štetni utjecaj na zdravlje ljudi.
Abstract (english)
The first chapter describes the basic theoretical settings of electromagnetism in the context of radiation at extremely low frequencies in an electric power system (50 Hz) where the magnetic and electric fields are not interconnected. The second chapter then states the basic mechanisms of coupling of time-varying electromagnetic fields and biological bodies and what are their effects on the human body. The biological effects of low-frequency fields and the sites of interaction and frequency of greatest sensitivity to various effects on the human body are reported. Finally, reference levels of exposure to time-varying electric and magnetic fields are given. The third chapter lists the methods of measuring magnetic fields - fluxgate, fluxmeter, NMR, ESR and the method of measuring electric fields (capacitive method). The last chapter deals mainly with LV induction electric motors and different ways of starting them. Then, the results of measurements are presented, which showed that the radiation of an induction motor in normal operation does not have a detrimental effect on human health.
