Abstract

UREDJAJ SA OPTIČKIM VLAKNOM ZA MERENJE JAČINE ELEKTRIČNE STRUJE, korišćenjem Faradejevog efekta, pri čemu magnetno polje koje okružuje provodnik 1 kroz koji teče struja utiče na stanje polarizovanosti svetlosti čiji put vodi kroz jezgro optičkog vlakna 2, koje u obliku namotaja 3 obmotava provod-nik 1, pri čemu se svetlost izvodjenja iz optičkog vlakna 2 deli cepačem 9 snopa na dva delimično svetlosna snopa, čiji se intenziteti 11, 12 po prolasku kroz po jedan polarizator 12, 11 mere po jednim fotodetektorom 14, 13, naznačen time, što su polarizatori (12, 11) simetrično zakrenuti jedan prema drugom, pri čemu se ugao (alfa) izmedju polarizatora (12, 11) i polarizacione ravni svetlosti uvedene u optičko vlakno (2), nalazi u opsegu izmedju +20В° i +40В°, odnosno izmedju -20В° i -40В°.
