Experimental Estimation of Journal Bearing Stiffness for Damage Detection in Large Hydrogenerators

Based on experimental pieces of evidence collected in a set of twenty healthy large hydrogenerators, this article shows that the operating conditions of the tilting pad journal bearings of these machines may have unpredictable and significant changes. This behavior prevents the theoretical determina...
