摘要： A fiber optic sensor system employs at least one light source that operates to generate light having one or more desired wavelengths. A first optical fiber based sensor transparent to a desired light wavelength operates to sense a magnetic field emitted from a predetermined electrical conductor or a current flowing through the electrical conductor. A temperature sensor that may be another optical fiber based sensor operates to sense an operating temperature associated with the first optical fiber based sensor in response to the light generated by the light source. Signal-processing electronics adjust the sensed current to substantially compensate for temperature induced errors associated with the sensed current in response to the measured operational temperature of the fiber optic sensor.

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.
