Abstract

L'invention concerne un procédé de protection d'une charge associée à une voie de disjonction d'une carte électronique de disjoncteurs statiques d'un système de distribution d'une puissance électrique d'un aéronef comportant une voie de disjonction (100) comprenant un microcontrôleur (112), un fusible (130) et un transistor à effet de champ (FET) à déplétion (132), le procédé comprenant les étapes consistant en : - un démarrage dudit système, - une mise à un état de fonctionnement prédéterminé du transistor FET à déplétion (132) de manière à générer un court-circuit entre une masse (134) de l'aéronef et une sortie (133) de la voie de disjonction - une détermination d'un disfonctionnement d'un composant de la voie de disjonction (100), et - un changement de l'état de fonctionnement du transistor FET à déplétion (132) en cas de disfonctionnement dudit composant de manière à faire fondre le fusible (130).
