Open the CIPO recordAbstract From the Canadian patent
The invention concerns a method for measuring the electrical characteristics of a telecommunication cable (10) comprising a bundle of electric wires (11) transporting an operating voltage (U) delivered by an equipment (15) with ground reference arranged in an insulating sheath comprising a conductive shield (12). The invention is characterised in that it comprises a step which consists in measuring the insulating resistance (R¿iso?) of the shield (12) relative to the ground a step which consists in determining a global insulating resistance (R¿i?) of the bundle of wires (11) relative to the conductive shield (12) from the result of the measurement of the insulating resistance (R¿iso?) and …

Why it's free to use
- Filed February 7, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 7, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 7, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
