Abstract

Système (16B-C), qui applique une tension ou un courant (35) antagoniste à un arbre (18) tournant pour minimiser un signal (24) de tension de mise à la terre de l'arbre, mesure (27) et analyse le signal antagoniste, et procure une logique (30) de système expert, qui compare les formes d'onde (42) apprises antérieurement et des modèles (44) de formes d'onde de ligne de base, de défaut et de dégradation à des formes d'onde fonctionnelles pour déterminer et prévoir des défauts et des dégradations (50).
