A power plant must keep up maintenance of the hydrogen-cooled generators for the safety of its workers and the environment, as well as for efficient operation of the plant. Traditional methods for hydrogen leak detection in a cooling system may be able to find the general area where hydrogen is present, but can be unreliable at finding the source of the leak. The introduction of optical gas imaging cameras has greatly improved the efficiency and performance of leak detection. With the addition of a dedicated thermal imaging camera for CO2 leak detection, utilities now have a way to efficiently find hydrogen leaks while using CO2 as a tracer gas.
