The system of magnetic flow sensor to measure the magnetic flux in a stator core, stator core for a generator of high voltage and stator bar

摘要

Abstract invention patent: "flow sensor for application in magnetic optical fiber rods of stator of generator of high voltage." The present invention relates to a magnetic flux sensor to measure the radial component of the magnetic flux focusing in a bar of the stator of a generator of high voltage.The magnetic flux sensor includes a fiber Bragg grating formed in the optical fiber and closed within a coating magnetostritivo. The coating magnetostritivo responds to changes in magnetic flux by applying deformation in fiber that changes the wavelength reflected from the Bragg grating that can be measured to provide a measurement of the flow.In one method, one or more of the magnetic flux sensors are positioned within an insulating layer of the stator bar.
