OSTI ID:6131366
This paper presents an on-line current monitoring system for detecting rotor faults in large high voltage 3-phase induction motors. The philosophy and practical advantages of current monitoring are discussed and samples of on-site case histories verify the effectiveness of the method for detecting broken rotor bars and air-gap eccentricity in the industrial environment. A new computerized diagnostic system with expert system capability is also described.
