Abstract
A device for detecting impedance disturbance points in symmetrical data transmission lines includes an evaluation unit having at least two magnetosensitive elements. One of these elements is positioned in the proximity of the first conductor strand and a second one is positioned in the proximity of the second conductor strand. The evaluation unit contains furthermore an evaluation circuit which is connected to the magnetosensitive elements and supplies at an output terminal a fault signal which provides information on impedance disturbance points in the data transmission lines.
