ABSTRACT:
A method and apparatus for detecting insulation failure in a machine is disclosed. The machine includes an input duct for receiving a cooling gas, a gas mixture region producing a mixed gas including the cooling gas and gas produced by the thermal decomposition of insulation within the machine, and an output duct for discharging the mixed gas. A first gas sample is obtained near the input duct and a second gas sample is obtained near the output duct. An analyzer is employed to assess the difference between the first sample and the second sample. This assessment detects potential thermal decomposition of the insulation within the machine. If thermal decomposition is present, a warning signal is provided.
