Question

RRB Paper · Accepted Answer

Hydrogen gas has a lower density than air, which means it can dissipate heat faster and more efficiently. It is also a good thermal conductor, allowing heat to be transferred quickly from the generator windings to the cooling system. In addition, hydrogen is non-toxic, non-corrosive, and non-reactive, which reduces the risk of fire or explosion in the generator. Finally, hydrogen is also lighter in weight than air, which means it reduces the overall weight of the generator and makes it easier to transport and install.

It offers reduced fire risk

It is light in weight

It is of high thermal conductivity
