description A contactless voltage sensing device configured to measure a voltage value of a conductor is provided. The contactless voltage sensing device includes a first impedance element having a first impedance, where the first impedance element is configured to be operatively coupled to the conductor. Further, the contactless voltage sensing device includes an antenna operatively coupled to the first impedance element, a second impedance element having a second impedance, where the second impedance element is formed in part by the antenna and a parasitic impedance element, and where the parasitic impedance element includes a parasitic impedance, and measurement and communication circuitry coupled to the first impedance element to measure the voltage value of the conductor. Il est décrit un dispositif de captage de tension sans contact dont la configuration permet de mesurer une valeur de tension dun conducteur. Le dispositif de captage de tension sans contact comprend un premier élément dimpédance ayant une première impédance configurée pour se coupler de manière fonctionnelle au conducteur. De plus, le dispositif de captage de tension comprend une antenne couplée de manière fonctionnelle au premier élément dimpédance, un deuxième élément dimpédance ayant une deuxième impédance, lequel deuxième élément dimpédance se forme en partie par lantenne et un élément dimpédance parasite, ainsi que des circuits de mesure et de communication couplés au premier élément dimpédance en vue de mesurer la valeur de tension du conducteur.
