CA 2650564

Certain exemplary embodiments can comprise an arc fault detection circuit. The arc fault detection circuit can comprise a zero crossing analysis sub-system comprising a counter configured to determine, for a first waveform, a count of dips that occur between a pair of predetermined zero crossings of a second waveform. The second waveform can be obtained from an electrical circuit.

Certains modes de réalisation de l'invention incorporent un circuit de détection d'arcs de court-circuit. Le circuit de détection d'arcs de court-circuit peut comprendre un sous-système d'analyse de passages par zéro comportant un compteur conçu pour compter, pour une première forme d'onde, un nombre de creux apparaissant entre une paire de passages par zéro prédéterminés d'une deuxième forme d'onde. La deuxième forme d'onde peut provenir d'un circuit électrique.
