Title (EN) DEVICE AND METHOD FOR MEASURING AN ALTERNATING VOLTAGE
(FR) DISPOSITIF ET PROCÉDÉ DE MESURE D'UNE TENSION ALTERNATIVE
Abstract: front page image
(EN)Measuring device, of the galvanic insulation type, to measure an alternating voltage (U1) of an electric mains line, comprising a measuring circuit (35), having a microcontroller, a supply circuit (33) able to supply the measuring circuit (35), and a transformer (T), having a primary winding powered by the mains sinusoidal voltage (U1), connected to said electric line, and a secondary winding with a voltage (U2), connected both to said measuring circuit (35) and also to said supply circuit (33). The supply circuit (33) and the measuring circuit (35) comprise respectively a first and a second full-wave rectifier elements (BRG, BRG'), distinct from each other, wherein the second rectifier element (BRG') is configured so as not to generate load effects on the secondary winding of the transformer (T), and the rectifier element (BRG') is loaded with a high value impedance (R').
(FR)L'invention porte sur un dispositif de mesure, du type à isolation galvanique, servant à mesurer une tension alternative (U1) d'une ligne de réseau électrique, comprenant un circuit de mesure (35) à microcontrôleur, un circuit d'alimentation (33) apte à alimenter le circuit de mesure (35), et un transformateur (T) ayant un enroulement primaire alimenté par la tension sinusoïdale du réseau (U1), connecté à ladite ligne électrique, et un enroulement secondaire ayant une tension (U2), connecté à la fois audit circuit de mesure (35) et audit circuit d'alimentation (33). Le circuit d'alimentation (33) et le circuit de mesure (35) comprennent respectivement des premier et second éléments redresseurs double alternance (BRG, BRG'), distincts l'un de l'autre, le second élément redresseur (BRG') étant configuré de manière à ne pas générer d'effets de charge sur l'enroulement secondaire du transformateur (T), et l'élément redresseur (BRG') étant chargé par une impédance à valeur élevée (R').
