Abstract

Ved måling av strøm i en leder (6) tilkobles en differentialforsterkers (1) to innganger lederen i to punkter (7, 8), som har en passende avstand. På denne måte unngås tapsgivende elementer ved målingen, samt bruk av strømomsluttende elementer. Strømforsyningen til differentialforsterkeren uttas symmetrisk i forhold til lederens potentiale. I tillegg til strømmen måles lederens spenning, og så vel som strøm som spenning tilføres A/D omformer. De digitaliserte signaler tilføres en beregningsenhet (5), hvilken er innrettet til å beregne lederens øyeblikkseffekt, øyeblikkesenergi, kvadratet på lederens strøm, strømmens kurveform, samt frekvensinnhold. Ovennevnte måleoppstilling er velegnet til styring av releer, sikringsutkoblinger, overstrømsbestemmelser samt som forbruksmåler til motorstyringer, og forsterkerkarakteristikk-overvåkning.
