Abstract

254,401. British Thomson-Houston Co., Ltd., and Whitaker, F. P. April 4, 1925. Coils and conductors; insulation.-To prevent the formation of corona at the ends of the slots when the windings of a high-voltage machine are being flashed, a corona shield 4 is provided which surrounds the conductors 1 within the slots and extends beyond the core 2, the outer end being embedded in insulating material 6. The shield, which mav consist of thin metal strip, is wound over the insulation 3 of the conductor and is electrically connected to the core laminations by means of a connector 5. The insulation 6 is of substantial thickness and may consist of a rubber compound moulded in position.
