1. A magnetic flux sensor system for measuring magnetic flux in a stator core of a high voltage generator, said flux sensor system comprising:

  • at least one magnetostrictive Bragg grating (MBG) sensor positioned relative to at least one stator bar in the stator core, said at least one MBG sensor including a fiber Bragg grating (FBG) formed in an optical fiber and an outer coating of a magnetostrictive material; and

    an analysis device providing an optical input signal to the optical fiber and receiving a reflected optical signal from the at least one MBG sensor, wherein the reflected optical signal provides a measurement of the magnetic flux from the stator bar.
