Abstract:
1. A method for servicing generators by uniformly aligning optical stripes on a circumferential area of a generator's rotor shaft comprising: measuring said circumferential area with a measuring element, wherein said measuring element flexibly laps said circumferential area; indicating on said measuring element the measurement of said circumferential area; determining the circumference of said circumferential area from said measuring element; dividing the circumference into a plurality of equally spaced segments; marking on at least one marking strip said plurality of equally spaced segments; aligning said at least one marking strip on the circumference of said circumferential area; creating a pattern of stripes on said circumferential area corresponding to said plurality of equally spaced segments on said at least one marking strip; and scanning said un uniformly aligned optical stripes with an optical probe to detect torsional forces in said rotor shaft.
