| 摘要 |
The present invention relates to a method for measuring the electrical characteristics of a telecommunication cable (10) comprising a bundle of electric wires (11) conveying a service voltage (U) delivered by equipment (15) referenced to ground, arranged in an insulating sheath comprising a conductive screen (12). According to the present invention, the method comprises one step of measuring the insulation resistance (Riso) of the screen (12) relative to the ground, one step of measuring the electric potential (Pe) of the screen (12) relative to the ground, and one step of determining a global insulation resistance (Ri) of the bundle of electric wires (11) relative to the conductive screen (12), using the result of the measurements of the insulation resistance (Riso) and of the electric potential (Pe) of the screen. Application to characterising or to maintaining telecommunication cables.
