Abstract: An apparatus for detecting a leak in a gas cooled generator is provided. The apparatus includes a subsystem for introducing a non-corrosive second gas having an infrared absorption spectrum into the generator. The apparatus also includes an imaging component adapted to detect radiation at the infrared absorption spectrum of the non-corrosive second gas. The imaging component is provided with a filter that filters wavelengths in a range encompassing the infrared absorption spectrum of the non-corrosive second gas. The imaging component displays an image of the tracer gas leaking from the generator on the imaging component.
