    Abstract: A method for preparing a field coil winding assembly including cleaning a plurality of copper coils followed by developing, after the cleaning, a copper oxide layer on each of the copper coils by oxidizing each of the copper coils in a solution. After the developing, each of the copper coils is rinsed followed by drying. After the drying, a turn insulation system is applied to each of the copper coils. The turn insulation system includes a turn insulation and an adhesive. The turn insulation includes at least one of a glass fiber re-enforced polyamideimide, a glass fiber re-enforced polyester, or a glass fiber re-enforced high temperature novolac epoxy. After the applying, each of the copper coils with the turn insulation system is cured. The plurality of copper coils with the turn insulation system are stacked in each of a plurality of rotor slots in a rotor.

    Abstract: An apparatus for detecting a leak in a gas cooled generator is provided. The apparatus includes a subsystem for introducing a non-corrosive second gas having an infrared absorption spectrum into the generator. The apparatus also includes an imaging component adapted to detect radiation at the infrared absorption spectrum of the non-corrosive second gas. The imaging component is provided with a filter that filters wavelengths in a range encompassing the infrared absorption spectrum of the non-corrosive second gas. The imaging component displays an image of the tracer gas leaking from the generator on the imaging component.
