ABSTRACT:
A method and apparatus for detecting imperfections in a semi-conductive strand shield applied to an electrical conductor. The method comprises the steps of applying AC current between a bare portion of the conductor and apparatus applying a jacket of insulating material over the strand shield, as the conductor and shield move through the apparatus. The current and the voltage applying the current are measured to determine the impedance of the circuit of the conductor and apparatus applying the insulating jacket. Changes in the impedance are then monitored, such changes being indicative of changes in the quality of the strand shield applied to the conductor.
