Abstract

Eine Messvorrichtung (100) zur Erfassung eines wechselspannungsführenden Leiters (180) umfasst eine Spannungsquelle (110) zur Erzeugung zweier phasenverschobener alternierender Spannungen, zwei komplexe Widerstände (125,130) mit ersten Anschlüssen, die mit den alternierenden Spannungen verbunden sind, und zweiten Anschlüssen, die miteinander verbunden sind und an denen eine Differenzspannung anliegt sowie eine Steuereinrichtung zur Steuerung der alternierenden Spannungen derart, dass ein zu den alternierenden Spannungen taktsynchroner Anteil der Differenzspannung betragsmäßig minimiert ist. Die Steuereinrichtung ist dazu eingerichtet ist, den Leiter zu erfassen, wenn das Verhältnis der alternierenden Spannungen nicht zu einem Verhältnis der komplexen Widerstände in Abwesenheit des Leiters korrespondiert. Dabei ist der zweite komplexe Widerstand mittels einer Steuerspannung veränderbar und es ist eine Sonde zur Bereitstellung der Steuerspannung in Abhängigkeit eines vom Leiter induzierten elektromagnetischen Wechselfeldes vorgesehen.
