CA 2193909

A ground fault detector for detecting a ground fault in an A.C. system including a power transformer having output secondary windings. The detector is comprised of apparatus for generating an isolated low voltage D.C. potential between ground and the secondary windings, apparatus for determining if a resistive leakage path is present between ground and a voltage output from the secondary windings, and shut-down apparatus for disconnecting the voltage output.

Détecteur de fuite à la terre utilisé pour découvrir une fuite à la terre dans un système c.a. Il comprend un transformateur d'alimentation possédant des enroulements secondaires de sortie. Le détecteur se compose d'un dispositif pour produire un potentiel continu isolé à basse tension entre la mise à la terre et les enroulements secondaires, d'un dispositif pour déterminer s'il y a une ligne de fuite résistive entre la mise à la terre et la tension en sortie des enroulements secondaires, et d'un dispositif de sectionnement pour déconnecter la sortie en tension.
