Title
(EN) DETERMINING ENERGY USAGE OF A RESIDENCE BASED ON CURRENT MONITORING
(FR) DÉTERMINATION D'UTILISATION D'ÉNERGIE D'UNE RÉSIDENCE BASÉE SUR UNE SURVEILLANCE DE COURANT
Abstract
(EN)
Systems and methods include determining energy usage of a residence from a current that flows through a first main conductor and a second main conductor that transport the current into the residence. Embodiments of the present disclosure relate to sensors (130a-b) that monitor magnetic fields (150a-b) generated by the first and second main conductors (120a-b). After a resistive load (210a-b) is added for an electrical path in the residence, the first and second magnetic fields (150a-b) may be converted to generate first and second calibrating currents. A first prototype current is corrected to eliminate the influence of the second magnetic field (150b) onto the first magnetic field (150a) and a second prototype current is corrected to eliminate the influence of the first magnetic field (150a) onto the second magnetic field (150b). The energy usage of the residence is determined from the corrected currents.

L'invention concerne des systèmes et des procédés faisant appel à une détermination d'utilisation d'énergie d'une résidence à partir d'un courant qui circule dans un premier conducteur principal et un second conducteur principal qui transportent le courant dans la résidence. Des modes de réalisation de la présente invention se rapportent à des capteurs (130a-b) qui surveillent des champs magnétiques (150a-b) générés par les premier et second conducteurs principaux (120a-b). Après l'ajout d'une charge résistive (210a-b) pour un trajet électrique dans la résidence, les premier et second champs magnétiques (150a-b) peuvent être convertis pour générer des premier et second courants d'étalonnage. Un premier courant prototype est corrigé pour éliminer l'influence du second champ magnétique (150b) sur le premier champ magnétique (150a), et un second courant prototype est corrigé pour éliminer l'influence du premier champ magnétique (150a) sur le second champ magnétique (150b). L'utilisation d'énergie de la résidence est déterminée à partir des courants corrigés.
