Abstract

Et seriematet lysovervåkingssystem, for eksempel for rullebanelamper på flyplasser. Ifølge oppfinnelsen erstat- tes store, kostbare og plasskrevende lavfrekvenstransformatorer med små høy- frekvenstransformatorer (T). Signalering og effektmating er atskilt ved hjelp av kapasitive og induktive komponenter (Cl, C2, LI). En høyfrekvensbryter (Sw) som er inkludert, benyttes for å skru på en lampe (B) ved oppbakking av den inn- matede lavfrekvenseffekt til høyfrek- vens, og dessuten for å signalere til- bake til sløyfens (SS) matepunkt.
