ABSTRACT:
Cooling means are provided for directly cooling the bore bus bars which connect a direct current exciter such as a bore pack exciter to the field of an electric power generator. Two bore bus bars are separated by an insulating sheet have a circular cross section, and are surrounded by an insulating cylinder. The bore bus bars include an axially extending slot adjacent the insulation to form passageways through which cooling gas flows to directly cool the bus bars and pass through the generator to the cooling unit.
