Abstract
A system for detecting a gas leak in a generator includes a source of carbon dioxide gas, and a subsystem for introducing the carbon dioxide gas into the generator. An infrared imaging device is adapted to communicate with a notification device to display an image of at least a portion of the generator and the carbon dioxide gas. The infrared imaging device is a cooled detector and a filter with a spectral response between about 3 μm and about 5 μm. At least one of the detector and the filter is cooled to between about −80° C. and about −200° C. The gas leak will be indicated on the notification device.
