CST11 - Catastrophic Failure Diagnosis with Modal Analysis of Generator Endwindings
Abstract
In this paper, the catastrophic failure of a 2-pole 360MW unit will be presented. This failure lead a root cause analysis and a series of investigations that was taken place in a similar design unit deployed at a different site. This paper will describe the bump test and modal analysis procedures and results that were carried out on the end of all coils of the stator winding in the sister unit of the failed 360MW generator which lead to conclusions that were crucial for the determination its failure root cause.
