ABSTRACT:
Methods and systems for cable inspection operate by generating a relative motion between an electrical cable including multiple wires and a magnetic field. An electrical signal induced in the wires is measured responsively to the magnetic field. A variation in the electrical signal is sensed due to the relative motion. In response to the variation, a defect is detected in the electrical cable.
