Abstract
A method and system for determining the status of power distribution cables which involves the removal of a plug from the sheath which is tiny relative to the size of the cable to expose an area of resistive material which may be probed to detect the presence or absence of a signal of predetermined frequency. The apparatus is equipped with self-testing circuits as well as circuits for determining resistance between the resistive layer and the sheath, whereby positive identification of the cable to be tested is assured. The apparatus is clamped directly to the cable and is controlled from a remote location, which protects the operator of the equipment. The plug removed from the sheath is cut and extracted by a tool which is also subject to remote control by the operator.
