Abstract | A ground fault circuit interrupter (GFCI) can include a current transformer (CT) comprising a single core, a first winding wound around the single core, and a second winding wound around the single core. The GFCI can include a ground fault (GF) detection module operatively connected to the first winding to receive signals from the first winding and configured to determine whether a line-to-ground fault exists. The GFCI can also include a GN stimulus operatively connected to the second winding to provide a GN stimulus signal to the second winding. The GFCI can also include a grounded neutral (GN) detection module operatively connected to second winding and configured to receive signals from the second winding to determine whether a neutral-to-ground fault exists.
Un interrupteur de circuit de fuite à la terre (GFCI) peut comprendre un transformateur de courant (CT) comprenant un noyau unique, un premier enroulement enroulé autour du noyau unique et un second enroulement enroulé autour du noyau unique. Le GFCI peut comprendre un module de détection de défaut à la terre (GF) connecté de manière fonctionnelle au premier enroulement afin de recevoir des signaux provenant du premier enroulement et conçu pour déterminer s'il existe un défaut phase-terre. Le GFCI peut également comprendre un stimulus de GN connecté de manière fonctionnelle au second enroulement afin de fournir un signal de stimulus de GN au second enroulement. Le GFCI peut en outre comprendre un module de détection de neutre mis à la terre (GN) connecté de manière fonctionnelle à un second enroulement et conçu pour recevoir des signaux provenant du second enroulement afin de déterminer si un défaut de mise à la terre du neutre. |
