  • Patent number: 7716817
    Abstract: A stator bar installation fixture and method for installing stator bars into specific stator core slots within a stator core of rotating electrical equipment. The stator bar installation fixture includes rotating mechanisms, rotatingly fixed at each end of the rotating electrical equipment, for supporting and controlling an angular positioning of a stator bar insertion mechanism relative to the stator core. The stator bar insertion mechanism supports a stator bar within the stator core, angularly locates a stator bar in alignment with the specific stator core slot, and inserts the stator bar into the specific stator core slot.
    Type: Grant

  • Patent number: 7449808
    Abstract: A stator bar series loop connection is provided that is comprised of a solidified stator bar and a stranded stator bar disposed in a stator slot so that one of the bars is disposed as a top bar and the other of the bars is disposed as a bottom bar in the slot. A first side plate is brazed adjacent a first end thereof to a first side of an end of the solidified bar and adjacent a second end thereof to a first side of the stranded bar. Further, a second side plate is brazed adjacent a first end thereof to a second side of the end of the solidified bar and adjacent a second end thereof to a second side of the stranded bar. Accordingly, the stranded bar is series connected to the solidified bar.

  • Patent number: 4891629
    Abstract: A binary gas analyzer instrument and analysis method for determining percent composition of a cooling gas within a turbine generator is disclosed. The instrument includes a measurement block having a plurality of cells therein, some of which comprise sealed cells containing a known reference gas. One of the cells comprises a measurement cell and contains the binary gas mixture to be evaluated. Each of the cells contains a thermistor and a heater is provided for keeping the cells at a substantially constant temperature. An electric current supply provides a constant current to each thermistor for selfheating, and the gas within each cell conducts heat away from the thermistor at a distinctive rate.
