Title
(EN) THE SMART CIRCUIT BREAKER FOR GRID CONNECTED RESIDENTIAL PHOTOVOLTAIC SYSTEMS
(FR) DISJONCTEUR INTELLIGENT POUR SYSTÈMES PHOTOVOLTAÏQUES RÉSIDENTIELS CONNECTÉS AU RÉSEAU
Abstract
(EN)
The invention provides an electronic circuit for carrying out at least three measurements, comprising at least one controller (10), at least three current sensors (54), at least three voltage sensors (55), and at least three relays (211). The smart circuit breaker (K) is used for the protection of photovoltaic systems, characterized in that it comprises at least one web connection unit (12), the circuit breaker control card (20), which triggers said circuit breaker (21), which provides detection of island mode, voltage collapse, and voltage jump.
(FR)
L'invention concerne un circuit électronique permettant de réaliser au moins trois mesures, ledit circuit comprenant au moins un dispositif de commande (10), au moins trois capteurs de courant (54), au moins trois capteurs de tension (55) et au moins trois relais (211). Le disjoncteur intelligent (K) est utilisé pour la protection des systèmes photovoltaïques, caractérisé en ce qu'il comprend au moins une unité de connexion Web (12) et la carte de commande du disjoncteur (20) qui déclenche ledit disjoncteur (21) assurant la détection d'un mode îlot, d'une chute de tension et d'un saut de tension.
