  • Abstract
    Relationships between shaft signals and eccentricities of salient-pole synchronous machines are studied. The magnitude and the thickness of shaft-signal loci reflect steady and dynamic eccentricities. Harmonic components of shaft signals closely relate to shorted field coils. Threshold records can be used for indications of changes in eccentricities and shorted field coils. Extensive experimental work agrees with the theoretical predictions
