ABSTRACT:
A testing apparatus for determining the integrity of an electrical cable. ccessive portions of electrical cable pass through an aqueous electrolyte with a distance measurement unit providing an indication of the position of a portion of the cable located in the electrolyte. A capacitance measurement unit connects to a selected conductor in the cable and to an electrode in the electrolyte to continuously generate a measured capacitance signal. An X-Y plotter produces an output that displays the measured capacitance as a function of the length of the cable passing through the electrolyte.
