Method and apparatus for monitoring the operation of an electric generator
First Claim
1. A method for monitoring the operating conditions of an electric generator, said method comprising the steps of:
- producing a first signal representative of vibration amplitude in end turns of stator windings of the generator;
producing a second signal representative of an electrical load under which said generator is operating;
comparing said first and second signals to stored reference data; and
producing an output signal based on the results of the comparing step, said output signal being representative of the operational status of the generator.

Abstract
A method and apparatus are provided for monitoring the operating conditions of an electric generator by producing a signal representative of vibration amplitude in end turns of stator windings of the generator; producing a signal representative of an electrical load under which said generator is operating; comparing the vibration and load signals to store reference data representative of normal or abnormal operating conditions; and producing an output signal based on a comparison of the vibration and load signals with the stored reference data. The output signal is representative of the operational status of the generator.
