SYSTEM FOR DETECTING COOLANT LEAKS IN GENERATORS
First Claim
1. A system for detecting a gas leak in a generator, the system comprising:
- a source of carbon dioxide gas;
a subsystem for introducing the carbon dioxide gas into the generator;
an infrared imaging device 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 comprising a cooled detector and a filter with a spectral response between about 3 μ
m and about 5 μ
m, wherein at least one of the detector and the filter is cooled to between about −
80°
C. and about −
200°
C.; and
wherein the gas leak will be indicated on the notification device.

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.
