  • Patent number: 9759630
    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 ?m and about 5 ?m. 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.

  • Patent number: 9488629
    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 ?m and about 5 ?m. 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.

  • Publication number: 20160202143
    Abstract: An on-deck system for non-destructively validating a machine part is provided. The machine part is configured for use with a dynamoelectric machine or a turbomachine. The system includes a portable and hand-held infrared transceiver configured to emit and receive infrared light, and a bandpass filter configured to filter the infrared light. A crystal probe is configured to contact the machine part, and one or more mirrors are configured to direct the infrared light onto the crystal probe and subsequently back to the infrared transceiver/detector. The infrared transceiver is adapted to communicate with a notification device configured to output a notification of a test result.

  • Patent number: 7913815
    Abstract: Disclosed is a solution to automate a seal oil float trap by-pass for a hydrogen cooled generator. An automated by-pass system is coupled to an existing manual by-pass system for a float trap for a hydrogen cooled generator. The automated by-pass system includes at least one solenoid valve and a controller that controls opening and closing of the solenoid valve. The automated by-pass system can also include manual valves, orifices and limit switches. The controller activates the solenoid valve to allow the seal oil to drain. The controller can also provide a notification alarm that the hydrogen cooled generator is being purged.
