Abstract

A method and an apparatus are provided to reduce or eliminate interference signals that have been additively superimposed on a useful signal for locating a cable sheathing fault of a buried electrical cable. A correction unit includes a filter, a delay device and/or a DC component estimator. The correction unit automatically determines a transient interference signal and a DC offset voltage component that have been superimposed on the useful signal as received in an input signal of the correction unit, and then subtracts these determined interference signals from the input signal to provide the interference-free or interference-suppressed useful signal as the output.
