1. A system to measure a temperature of a component of an electric machine, the system comprising:
- an optical fiber disposed proximate to the component;
at least one sensor, disposed along the optical fiber, to detect the temperature of the component; and
a data acquisition system operably coupled to the at least one sensor via the optical fiber to generate real-time data in accordance with the detected temperature of the component during an operation of the electric machine.

15. A system to measure temperatures of components of an electric machine, the system comprising:
-
a first set of sensors, disposed along optical fibers and dispersed from one another at a first interval in a predetermined direction relative to the components, to each detect a temperature of corresponding local portions of the components; a second set of sensors, disposed along optical fibers proximate to a hot-spot of the components and dispersed from one another at a second interval in the predetermined direction, to each detect a temperature of corresponding local portions of the components; and a data acquisition system operably coupled to each of the first and second set of the sensors via the optical fibers to generate real-time temperature data in accordance with the detected temperatures.

16. A method of operating an electric machine by monitoring temperatures of components thereof, the method comprising:
-
installing a set of optical fibers, including sensors configured to detect temperatures of the components, at various positions proximate to the components; and interrogating each of the sensors so as to generate real-time temperature data of the components, while the electric machine is in operation, in accordance with the detected temperatures. - View Dependent Claims (17, 18, 19, 20)
