Abstract
A system including: a cable including: a core capable of transporting at least one useful electric signal; a sheath surrounding said core; at least one conductive wear detection strand embedded in the sheath and substantially extending along the entire length of the cable; and at least one reference conductive element which is not connected to said at least one wear detection strand and substantially extends along the entire cable length; and a control unit capable of measuring the capacitance or the resistance formed between said at least one strand and the reference conductive element.
