Abstract

Le dispositif comprend un transformateur 3 à circuit magnétique et deux composants écrêteurs, les diodes de Zener Z1 et Z2, disposés en tête-bêche entre les bornes de sortie du transformateur. Les enroulements primaire 1 et secondaire 2 du transformateur sont bobinés perpendiculairement selon des axes dont l'intersection est située au point milieu de l'un des enroulements de manière à ce que le couplage mutuel soit nul à la saturation. Applicable principalement pour assurer la protection des équipements téléphoniques contre les surtensions de toute origine.
