Hydrogen gas has a superior cooling property and generators of rating below 500 MW are cooled using a hydrogen cooling system. The ratio of hydrogen and air is marinated in the hydrogen cooling system to avoid an explosion. The hydrogen-to-air ratio of 9:1 is used in a large rating generator.
The air is enclosed in the system and just keeps re-circulating in the internal parts of the generator. The hot air is cooled by using water heat exchangers. Which helps to maintain the temperature of the machine. In this method, the same air is used again and again for cooling the circuit. 2. Water Cooling Generator:
Closed-circuit cooling functions like a closed loop system wherein the hot air released by the generator is cooled by a water-cooled heat exchanger, and the cooled air from the heat exchanger is then sent back to the generator or alternator via fans in order to cool the generator from within.
The cooling path provided by the fans is mounted at each end of the generator rotor. The above diagonal flow cooling method is used for two-pole generators. For four-pole generators, the radial flow cooling method is used. 3. Hydrogen Cooling Generator:

Open-circuit cooling functions by forcing air through the generator machine via fans or blowers and circulating the air drawn inside the generator. The air drawn into the generator is then dissipated out
