Influence of Turbine Load on Vibration Pattern and Symptom Limit Value Determination Procedures

Vibration-Based Diagnostics of Steam Turbines

“…Some attention has been paid to developing experimental relations of the S i = f(P u ) type (see e.g. Gałka, 2001), bearing in mind that they are approximate and applicable to a given turbine type only. Such relations turn out to be strongly non-linear and differences between individual symptoms are considerable.…”
