Abstract

Es werden ein Verfahren und eine Vorrichtung (10) zur Ermittlung von Inhomogenitäten des Schirmverhaltens geschirmter (12) elektrischer Leitungen (11) vorgeschlagen. Das Verfahren umfaßt folgende Verfahrensschritte: a. Anlegen eines Frequenzsignals (13) vorbestimmbarer Frequenz und Spannungsamplitude an den Schirm (12) des Leiters (11), b. sensorische (14, 15) Erfassung des durch das Frequenzsignal (13) erzeugten elektrischen und/oder Magnetischen Feldes des Schirmes (12) in definiertem Abstand zum Schirm (12) an im wesentlichen gegenüberliegenden Orten des Schirms (12) und Ausbildung eines entsprechenden elektrischen und/oder Magnetischen Feldsignalpaares (18, 19), c. jeweilige Gleichrichtung der Signale des elektrischen und/oder Magnetischen Feldsignalpaares (18, 19), d. Bildung eines Differenzsignals (20) aus den gleichgerichteten elektrischen und/oder Magnetischen Feldsignalen (18, 19) und e. Bewertung des Differenzsignals (20) als Funktion der ermittelnden Inhomogenitäten des Schirmverhaltens des geschirmten elektrischen Leiters (11).
