Title
(EN) A METHOD AND A DEVICE FOR DETERMINING THE LOCATION OF A PARTIAL DISCHARGE (PD)
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE LOCALISER UNE DECHARGE PARTIELLE (DP)
Abstract
(EN) The invention relates to a method and a device for determining the location of a partial discharge (PD) in a transformer or a reactor, in which signals produced by a partial discharge are detected and supplied to an evaluation device. The invention provides a method and a device that makes possible straightforward, rapid and accurate location of partial discharges in a transformer (or reactor). It can be used for PD location of a transformer at test or for on-line monitoring supervision.
(FR) La présente invention concerne un procédé et un dispositif permettant de localiser une décharge partielle (DP) dans un transformateur ou dans un réacteur, dans lequel les signaux produits par une décharge partielle sont détectés puis fournis à un dispositif d'évaluation. Cette invention concerne également un procédé et un dispositif permettant la localisation directe, rapide et précise de décharges partielles dans un transformateur (ou un réacteur). Le mode de réalisation décrit dans cette invention peut être utilisé pour localiser une décharge partielle d'un transformateur soumis à un test ou dans le cadre d'une supervision de contrôle en ligne.
