Abstract
A method for determining the radial deformation of a blade in a turbine that includes: 1) taking an initial measurement of the blade with one or more proximity sensors disposed around the circumference of a stage of blades; 2) after the initial measurement, taking a second measurement of the blade with the one or more proximity sensors; 3) making a determination of the radial deformation of the blade by comparing the initial measurement to the second measurement. The initial measurement and the second measurement may be taken while the turbine is operating.
