Abstract
A system is provided for monitoring a relative displacement of a pair of end-winding components. The system includes a structure mounted to the end-winding components. The system further includes a fiber Bragg grating mounted to a non-curved surface of the structure, where the fiber Bragg grating is configured to reflect incident radiation having a peak intensity at a respective wavelength based on a strain of the fiber Bragg grating. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the pair of end-winding components.
