METHOD AND 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 a non-corrosive tracer gas;
a subsystem for introducing the non-corrosive tracer 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 non-corrosive tracer 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 and method for detecting a gas leak in a generator is provided. The system includes a source of a non-corrosive tracer gas, and a subsystem for introducing the non-corrosive tracer gas into the hydrogen cooled generator. An infrared imaging device is adapted to communicate with a notification device to display an image of at least a portion of the hydrogen cooled generator and the non-corrosive tracer gas. The infrared imaging device includes a cooled detector, and a filter with a spectral response between about 3 μm and about 5 μm. The detector and/or the filter is cooled to between about −80° C. and about −200° C. The gas leak will be indicated on the notification device. The generator may hydrogen cooled, and on-line or on-grid.
