Abstract

Et 3-fase luftledningsbasert fordelingsnett opererer på en mellomspenning (f.eks. 11 kV til 33 kV), mellom et høyspenningstilførselsnett (på f.eks. 110 kV eller 275 kV) og et forbrukemett system (på f.eks. 110 V eller 230V). Et signaleringssystem anvender signaler på frekvenser fortrinnsvis i området 10 kHz - 100 kHz for signalering over nenet, idet signalene kobles induktivt til og fra nettet. Signalene kobles til forskjellige faser på forskjellige punkter i nettet, idet krysskobling mellom fasene sikrer at signaler som kobles til systemet på én fase gir adekvat signalstyrke for deteksjon ved andre punkter i systemet uansett hvilken fase detektoren er koblet til.
