Abstract
Apparatus and method for monitoring torsional vibration in the rotor of a dynamoelectric machine by detecting electrical quantities available at the output terminals of the machine. For at least one phase of the machine, output voltage and current are detected and a composite signal is formed therefrom in signal processing circuitry. The composite signal is in synchronous phase with the mechanical angle of the rotor and may be demodulated to obtain the torsional vibration information.
