Abstract
The invention is an apparatus for measuring the volume of water intrusion underwater cables without dissecting the cables. The apparatus comprises a novel arrangement of a capacitive test fixture and an electrical impedance analyzer to provide measurement of the volume of water in a cable based on cable capacitance. The capacitive test fixture measures the electrical capacitance along the cable as the cable is fed through the test fixture.
