Behavior of Eccentric Rotors Through the Critical Speed Range

We also recently published and presented a new paper at the MFPT 2015 conference, providing a proven outage strategy for planned work on turbine-generator rotors, to be able to guarantee a smooth restart without the need for field balancing. The paper details crucial and often-neglected procedures that must be incorporated into a planned outage scope to properly identify and address all potential sources of rotor vibration.
