Hydrogen Measurement in Hydrogen-Cooled Turbo Generators
With its low viscosity and high specific heat, hydrogen is the best gas available and is therefore used in large generators where the cooling requirements are severe.

Hydrogen-cooled turbo generator
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
