This document discusses generators customized for gas and steam turbines. It describes 2 pole generators that are available with different cooling systems like TEWAC, CACA, and DAC. Technical specifications are provided for frequency, power factor, and efficiency for 50 Hz and 60 Hz generators. Generators with water-cooled stators and hydrogen-cooled rotors are described as optimal for high output applications up to 1270 MVA in large steam power plants due to their compact design and direct water-cooled stator.
