Abstract
The present invention provides a high voltage generator stator coil for power generation systems for preventing partial discharge. The high voltage generator stator coil preferably includes a plurality of metal strands that form a high voltage conductor, conductive resin-rich filler material positioned to make electrical contact with the plurality of metal strands, a conductive inner corona protector positioned to electrically contact and overlie the conductive resin-rich filler material, groundwall insulation positioned to overlie and surround the conductive inner corona protector, and a conductive outer corona protector positioned to overlie and surround the groundwall insulation. The present invention also provides a method for forming a high voltage generator stator coil. The method preferably includes abuttingly contacting a plurality of metal strands in a stacked configuration to thereby form a high voltage conductor having at least a substantially straight portion. The method also includes the step of positioning a conductive resin-rich fleece filler material to electrically contact the high voltage generator stator coil, positioning a conductive inner corona protector to overlie and electrically contact the conductive resin-rich fleece filler material, positioning groundwall insulation to overlie and surround the conductive inner corona protector, and positioning a conductive outer corona protector to overlie and surround the groundwall insulation.
