Detecting Stator Winding Bar Vibration with On-Line Partial Discharge Measurements – paper

Published Jul 11th, 2022 IRMC 2022 - Osmo Koponen

In this paper two real-life cases of generator stator winding bar vibration problem and their consequent failures are discussed.
The emphasis is on the analysis of on-line partial discharge measurement results and how the bar vibration phenomenon affects the partial discharge phenomenon of a high voltage generator and how it can be recognized.
