Abstract:
1. An apparatus for detecting a leak locale in stator liquid cooling system of a liquid cooled generator, the apparatus comprising: a subsystem for introducing a pressurized non-corrosive gas having an infrared absorption spectrum into a plurality of stator windings of the stator liquid cooling system; and an imaging component adapted to detect radiation at the infrared absorption spectrum of the pressurized non-corrosive gas, the imaging component having a filter that filters wavelengths in a range encompassing the infrared absorption spectrum of the pressurized non-corrosive gas, wherein the subsystem for introducing the pressurized non-corrosive gas comprises means for draining liquid coolant from the plurality of stator windings; means for drying the plurality of stator windings with air; and means for introducing a mixture of air and carbon dioxide at a predetermined temperature, wherein the mixture of air and carbon dioxide has a content ratio of carbon dioxide of between 0.1% to 100%.
