B8.4 - Characterization of Fiber Bragg Grating Sensor in a High Speed Rotating Pipe

R. Ramalingam & H. Neumann
The next generation generators will use high temperature superconductors (HTS) for its rotor construction replacing currently used conventional copper rotor. This will enhance the generator efficiency to a steep increase of 0.5% which results in saving of $ 3.8 M for 900 MVA Generator according to calculation done in 2007. The HTS rotor, rotates at 3600 rpm will be cooled by liquid Neon to 30 K using cooling channel arrangements. The temperature profile of the...
