Abstract: Generator stator bar having profile strip and process for manufacturing a generator stator bar are presented. The generator stator bar includes stator bar strands assembled together. The profile strip is placed on top side and bottom side surfaces of the stator bar strand assembly. The profile strip includes uncured strip consisting of uncured material. The profile strip includes pre-cured strip consisting of pre-cured material. The pre-cured strip includes cavities perforated through its thickness. The profile strip enables the generator stator bar to be manufactured by a single press and heat operation to achieve a rectangular geometry having round outer edges and to maintain orientations of stator bar strands parallel to the profile strip.

Abstract: A magnetic flux sensor for measuring the radial component of the magnetic flux impinging on a stator bar of a high voltage generator. The magnetic flux sensor includes a fiber Bragg grating formed in an optical fiber and enclosed within a magnetostrictive coating. The magnetostrictive coating responds to changes in magnetic flux by applying a strain on the fiber that changes the reflected wavelength of the Bragg grating that can be measured to provide a measurement of the flux. In one embodiment, one or more of the magnetic flux sensors is positioned directly within an insulating layer of the particular stator bar.
