Patent

CA 2542724

A microcontroller-based temperature compensated circuit for ground-fault circuit interrupter to meet the requirements of UL 943 using a single sensor to detect both ground-fault and grounded-neutral fault conditions in both full- wave and half-wave AC power supplies as part of a ground-fault circuit breaker or a receptacle device.

L'invention se rapporte à un circuit à compensation de température fondé sur un microcontrôleur pour un interrupteur de circuit à défaut à la terre afin de satisfaire aux exigences de UL 943 au moyen d'un seul détecteur afin de détecter à la fois les conditions de défaut à la terre et les conditions de défaut neutres à la terre dans les alimentations de courant CA pleines ondes et demi-ondes comme faisant partie d'un disjoncteur de circuit à défaut à la terre ou d'un dispositif réceptacle.
