Abstract :
A substantial improvement in the current carrying capacity of turbine-generator rotors is made possible by circulating the cooling medium directly in contact with the copper conductors. This system also permits effective use of higher hydrogen pressure and is applicable to units of large specific ratings without appreciably modifying operating procedure. Additional gains may be obtained similarly by applying the cooling scheme to stator coils.
