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 &#x3bc;m and about 5 &#x3bc;m. At least one of the detector and the filter is cooled to between about &#x2212;80&#xb0; C. and about &#x2212;200&#xb0; C. The gas leak will be indicated on the notification device.

System for detecting coolant leaks in generators

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 &#x3bc;m and about 5 &#x3bc;m. The detector and/or the filter is cooled to between about &#x2212;80&#xb0; C. and about &#x2212;200&#xb0; C. The gas leak will be indicated on the notification device. The generator may hydrogen cooled, and on-line or on-grid.

Method for detecting coolant leaks in generators

Embodiments include a system having a turbine support key having a set of key segments selectively stackable together in a plurality of combinations to adjust a thickness between turbine supports based solely on a selection of the key segments from the set.

System and method for aligning turbine components

A system and method for monitoring a pilger mill having a crankshaft driving rolls with a reciprocating motion to reduce a tube over a mandrel. A linear sensor coupled to the mandrel supplies a mandrel position signal. A rotary sensor coupled to the crankshaft supplies a crankshaft angle signal. A processor for combining the mandrel position signal and the crankshaft angle signal provides a mandrel motion signal characteristic of the tube reduction.
