Abstract

Procédé pour la correction automatique du point zéro et de l'étalonnage des kilowattheuremètres électroniques. A des intervalles de temps suffisants, on met par l'intermédiaire d'un commutateur électronique, les entrées du compteur au potentiel zéro et, lors de la mesure suivante, on détermine et on mémorise l'écart par rapport à la valeur de consigne, à des intervalles de temps suffisants, on applique les entrées du compteur sur une ou plusieurs grandeurs de référence, et lors de la mesure suivante, on détermine et on mémorise l'écart par rapport à la valeur de consigne et, lors de la mesure de la consommation d'énergie, on utilise les deux valeurs de correction mémorisées pour compenser toutes les erreurs du pont zéro et d'étalonnage.Method for automatic zero point correction and calibration of electronic kilowatt-hour meters. At sufficient time intervals, the counter inputs are set to zero potential by means of an electronic switch and, during the next measurement, the deviation from the setpoint is determined and stored, at sufficient time intervals, the counter inputs are applied to one or more reference quantities, and during the next measurement, the deviation from the setpoint is determined and stored in memory and, when measuring energy consumption, the two stored correction values are used to compensate for all zero bridge and calibration errors.
