Maintenance of hydrogen-cooled generators is critical for the safe and
efficient operation of a power plant. Finding and repairing hydrogen
leaks from the cooling system is one aspect that can require exhaustive
searches on components, valves, fittings, or other locations.
Traditional methods for hydrogen leak detection tend to be unreliable at
finding the source of the leak, but optical gas imaging cameras have improved the efficiency and performance of leak detection a great deal.
