Estimating the term…
A sensor measures temperature in stationary components of electrical machines using fiber optics. An optical fiber is embedded in a non-metallic ribbon. Notches are cut in the ribbon to effect bends that accommodate a shape of a stationary component. The ribbon and optical fiber are attached to the stationary component. A series of laser pulses can be injected from at least one end of the optical fiber, and the stationary component temperature can be monitored by interrogation of reflections from the series of laser pulses.
A method of measuring temperature in stationary components of electrical machines using fiber optics, the method comprising:
An apparatus for measuring temperature in stationary components of electrical machines, the apparatus comprising an optical fiber embedded in a non-metallic material ribbon, wherein notches are formed in the ribbon in a width direction to accommodate bends in a stationary component, and wherein the ribbon is formed of a material with sufficient creep strength to support the optical fiber while preventing the optical fiber from being crushed.
