A method for monitoring the operating conditions of an electric generator including the entire stator core and all winding components for conditions of mechanical strain and temperature throughout the machine by means of distributive fiber optic sensors based on both Rayleigh back scattering techniques and Brillouin frequency shift fiber optic sensor analysis both of which do not have the gaps and limitations associated with standard fiber Bragg grating fiber optic point sensors, by virtue of the fact that both Rayleigh and Brillouin scans and allow accurate strain and temperature determinations at all points along standard fiber optic cables of considerable length, approximately two kilometers in the case of the Brillouin, which effectively yields many tens of thousands of sensors throughout the entire standard fiber optic cable. Raman distributive temperature sensing also has a limited application. Single mode and polarizing maintaining fibers can both be analyzed and read with any Rayleigh or Brillouin distributive fiber optic sensor laser system allowing great flexibility in sensor spatial resolution, total sensed length, resolution and other factors not possible with conventional fiber Bragg gratings. A sealed fiber collection box located outside the electric generator permits enhanced reliability and reconfiguration into any number of desirable fiber layouts necessary for specific static and dynamic measurements in an optimal manner.
