ABSTRACT:
A method and apparatus is disclosed for detecting insulation faults in the insulation of wires being stranded into cable. A voltage is applied to a bead-chain electrode through which the wires are passed, a signal pulse generated upon voltage breaking down between the electrode and a wire, and the simultaneous presence of signal pulses in two or more wires detected. In this manner adjacent insulation faults in two or more wires may be recognized.
