Title
(EN) DIELECTRIC MATERIAL FOR A HIGH VOLTAGE CAPACITOR
(FR) MATÉRIAU DIÉLECTRIQUE POUR UN CONDENSATEUR HAUTE TENSION
Abstract
(EN) A high voltage capacitor for a voltage divider is described that is configured to sense an elevated voltage for medium and high voltage electrical distribution networks. The high voltage capacitor comprises a high voltage electrode, a measurement electrode, and an dielectric material disposed between the high voltage and measurement electrodes, wherein the dielectric material comprises first and second dielectric fillers disposed in an insulating polymer matrix such that the change in capacitance of the dielectric does not vary by more than +/- 0.5% in the temperature range of –30°C to 60°C and the high voltage capacitor has a withstand voltage of at least 50 kV.
(FR) L'invention concerne un condensateur haute tension pour un diviseur de tension qui est configuré pour détecter une tension élevée pour des réseaux de distribution électrique moyenne et haute tension. Le condensateur haute tension comprend une électrode haute tension, une électrode de mesure et un matériau diélectrique disposé entre les électrodes haute tension et de mesure, le matériau diélectrique comprenant des première et seconde charges diélectriques disposées dans une matrice polymère isolante de telle sorte que le changement de capacité du diélectrique ne varie pas de plus de +/- 0,5 % dans la plage de température de – 30 °C à 60 °C et que le condensateur haute tension a une tension de tenue d'au moins 50 kV.
