Abstract

L'invention concerne un appareil de simulation de charges électriques. L'appareil selon l'invention se comporte comme une charge électrique classique vis-à-vis d'un dispositif de mesure de puissance qui doit etre vérifié, mais il est portatif et dissipe très peu d'énergie et de chaleur. Une source de courant crée un signal de courant variable sélectivement de tension relativement faible, une source de tension crée un signal de tension variable sélectivement, verrouillé en phase sur le signal de courant et ayant une intensité constante relativement faible. Le déphasage peut être réglé. Application à la vérification des appareils de mesure de puissance.
