Patent

CA 2654135

Methods and techniques are disclosed for an intelligent GFCI device (IGFCI) having a microcontroller programmed to perform self-testing on a periodic basis and communicate the results of this testing to a remote monitoring device such as a remote central logging computer. In some implementations, with two-way (bidirectional) communication, a plurality of self-testing IGFCI devices can be tested and reset systematically from a remotely located device to reduce disruption to users. The IGFCI device can be configured to be automatically reset or manually reset upon the application of AC power to the device.

L'invention concerne des procédés et des techniques pour un dispositif GFCI intelligent (IGFCI) ayant un microcontrôleur programmé pour réaliser un autotest sur une base périodique et communiquer les résultats de ce test à un dispositif de surveillance distant tel qu'un ordinateur distant de journalisation centrale. Dans certaines mises en AEuvre, avec une communication à deux sens (bidirectionnelle), une pluralité de dispositifs IGFCI autotesteurs peuvent être testés et réinitialisés systématiquement depuis un dispositif situé à distance pour réduire une perturbation pour des utilisateurs. Le dispositif IGFCI peut être configuré pour être réinitialisé automatiquement ou manuellement lors de l'application d'une puissance CA sur le dispositif.
