Abstract

A találmány tárgya mérőáramkör-elrendezés (1) közvetlencsatlakoztatású villamos fogyasztásmérőkhöz, amelynek egyfeszültségmérő bemenete (3) és egy árammérő bemenete (4) van, azárammérő bemenetre (4) egy galvanikus leválasztás céljából egyfeszültségváltón (5) keresztül egy mérősönt (Rsn) csatlakozik és atalálmány szerint a feszültségváltó (5) a mérősönt (Rsn) felé egyohmos ellenállást mutat, amely egyrészt a szabványnak megfelelőenkellő mértékben korlátozza a feszültségváltó (5) egyenáramúigénybevételét és másrészt ez az ohmos ellenállás elég kis értékűahhoz, hogy a feszültségváltó (5) induktivitásával együtt csak egy, aszabvány áltat megengedett szöghibát tegyen lehetővé.
