  1. PATENTNI ZAHTEVKI 1. Naprava z optičnimi vlakni za merjenje jakosti električnega toka z izkoriščanjem Faradayevega efekta, pri čemer magnetno polje, ki obkroža na visoko napetostni potencial priključeni vodnik (1), skozi katerega teče tok, vpliva na stanje polarizacije svetlobe, čigar pot vodi skozi jedro optičnega vlakna (2), ki obkroža vodnik (1) v obliki navitja (3), pri čemer je na enem koncu (4) optičnega vlakna (2) predvidena odbojna ploskev (5), medtem ko poteka na njegovem drugem koncu (6) vklop in izklop svetlobe, označena s tem, da na optično vlakno (2) vtisnemo krožni dvojni lom z zasukanjem okoli njegove podolžne osi, da je en konec (4) optičnega vlakna (2) postavljen z odbojno površino (5) v neposredno bližino njegovega drugega konca (6), tako da predstavlja celotno vlakno (2) skoraj popolnoma sklenjeno pot in da oba končna dela optičnega vlakna (2) ležita neposredno drug poleg drugega in vzporedno.
