V- TION SOURCES IN TURBO GENERA TOR COMPONENTS THEIR EFFECTS ON "OLE V~ TION LEVEL

In this paper the following subjects are discussed briefly 1- Vibration Reasons in Turbo generators as whole. 2- Vibration Sources in Turbo generators components such as stator core and windings, rotor core and windings. .... etc. 3- Vibration types e.g vertical and horizontd vibrations and their creation reasons. In this section the mechanical and electromagnetic reasons am mentioned 4- Trouble shooting How eh~ seen from operational sight of view.
