Hydrogen Cooling System in Electric Generators

It is undeniable that an electric generator must have an excellent cooling system to dissipate the heat created in it. If the heat inside the generator is not discharged immediately, it will directly damage the generator itself. Excessive heat can extreme damage the rotor coil, the stator, and will even burn the components of the generator.

Air becomes a popular medium used to cool generators. The abundant and inexpensive amount is a strong reason to continue using it. However, the air conditioning system used in the generator turned out to save weaknesses. The air is unable to cool the generator with a capacity above 425 Megawatts. In addition to its insufficient heat conductivity, its density is too heavy to be another disadvantage. For this reason, other types of gas are needed which are better in terms of thermal conductivity and other characteristics.

Hydrogen gas is the best choice to replace air as a generator cooling medium, especially for large …
