A cable accessory device, including a one-way conducting element and a grounding electrode. One end of the one-way conducting element is connected to a conductor structure in a cable, and the other end is connected to the grounding electrode. By applying voltages with different polarities to the one-way conducting element, the one-way conducting element is enabled to have different on / off states. When the on / off state of the one-way conducting element is an on state, the conductor structure in the cable is connected to the grounding electrode via the one-way conducting element, so as to measure direct current resistance of the conductor structure. Moreover, when the on / off state of the one-way conducting element is an off state, the one-way conducting element breaks connection between the conductor structure and the grounding electrode, so as to measure insulation resistance of an insulation structure. In this way, tests for measuring direct current resistance of the conductor structure and insulation resistance of the insulation structure may be facilitated, so that failures of the cable may be comprehensively investigated to damages in the cable may be found in time, thus reducing subsequent costs in locating and maintenance.
