Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system for monitoring a relative displacement of a pair of end-winding components.SOLUTION: The system includes: a structure mounted to the end-winding components 102 and 104; and a fiber Bragg grating 116 mounted to a non-curved surface 126 of the structure, wherein the fiber Bragg grating 116 is configured to reflect incident radiation having a peak intensity at respective wavelengths based on a strain of the fiber Bragg grating 116. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating 116 within a predetermined range over a span of the relative displacement of the pair of end-winding components 102 and 104.
