Abstract

A procedure and a system for the evaluation of the quality and/or efficiency of a cable or a cable segment by a current measurement is disclosed. This is achieved by supplying between the core and the screen of a cable a voltage with alternating polarity and rectangular shape. The periodic duration' of this voltage is selected in a way so as to permit the current measurement of the charge current shortly before a polarity reversal, providing a current value equal to the leakage current.
