Generators in power plants, especially turbo generators, are cooled with hydrogen. During operation, the rotor and strator generate heat. This heat is
The absence of oxygen in the atmosphere within significantly reduces damage to the winding insulation from corona discharges; these can be problematic as the generators typically operate at high voltage, often 20 kV. The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto
In its pure state, hydrogen is fine, but a mixture of air and hydrogen can be explosive. Then, why hydrogen? Operating an electric power generator produces large amounts of heat that
