    摘要： An electrical machine component monitoring system includes a light source that provides an optical signal through a fiber optic cable and a fiber optic sensing component positioned on the electrical machine component or at a standoff distance from the electrical machine component to obtain a responsive optical signal representative of a condition of the electrical machine component. The system further includes a photodetector to receive the responsive optical signal from the fiber optic sensing component and to convert the responsive optical signal to an electrical signal. A processing circuitry is also provided in the system for determining information regarding dirt on the electrical machine component by analyzing the electrical signal.

    摘要： A system is provided for monitoring a relative displacement of a pair of end-winding components. The system includes a structure mounted to the end-winding components at an angle with respect to the end-winding components for monitoring the relative displacement. The system further includes an optical fiber with a first portion including a fiber Bragg grating mounted to a surface of the structure to experience a strain resulting from a strain of the structure due to the relative displacement. The optical fiber includes a second portion internally routed through in the structure to the first portion mounted to the surface. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the end-winding components.

    摘要： An optical gamma thermometer includes a metal mass having a temperature proportional to a gamma flux within a core of a nuclear reactor, and an optical fiber cable for measuring the temperature of the heated metal mass. The temperature of the heated mass may be measured by using one or more fiber grating structures and/or by using scattering techniques, such as Raman, Brillouin, and the like. The optical gamma thermometer may be used in conjunction with a conventional reactor heat balance to calibrate the local power range monitors over their useful in-service life. The optical gamma thermometer occupies much less space within the in-core instrument tube and costs much less than the conventional gamma thermometer.
