Abstract

U magistarskom radu opisan je način rada, te postupak izrade senzora za mjerenje magnetske indukcije i magnetskog polja. Također je opisan postupak umjeravanja senzora, te je obavljena usporedba mjerenja magnetske indukcije Hallovim senzorom i mjernim svitkom. Senzori su ugrađeni na konkretnom objektu, a radi se o prototipu generatora vjetroelektrane snage 1 MVA. Uz opis mjernog objekta dan je i prikaz mjernih mjesta. Na mjestima ugradnje senzora programom za proračun metodom konačnih elemenata izračunati su valni oblici signala u svrhu njihove usporedbe s podacima mjerenja. Detaljno su razrađeni rezultati mjerenja u praznom hodu, a djelomično i u kratkom spoju. Rezultati dobiveni proračunom i mjerenjem prikazani su i međusobno uspoređeni.

Abstract (english)

This paper describes the working principle and how to make a sensor for measuring of magnetic induction, and magnetic field. Also it is shown how to calibrate sensors, and comparison of Hall sensor and measuring coils. Sensors are mounted on 1 MVA wind–power generator prototype. Measuring object has been described along with places of measuring interest. Dynamic electromagnetic field computing results are made, shown through application of finite element method on the generator model. Measuring results are detaily explained and analysed for no load test, and partly for short circuit test. Results gained by computing and measuring and compared and presented.
