Abstract

815,489. Transformer arrangements. ALLMANNA SVENSKA ELEKTRISKA A.B. March 26, 1956 [March 30, 1955], No. 9287/56. Class 38 (4). An additional transformer winding 9 is inserted between one end of the H.T. winding 4 of a mains transformer and earth to raise the H.T. potential. A second secondary winding 10 is connected in series (antiphase) with a L.V. load fed from a tap 6 on winding 4 to restore the normal voltage relation of the L.V. supplies.
