Abstract

279,705. British Thomson-Houston Co., Ltd., and Holbrook, H. S. March 31,1927. Polyphase transformers; regulating. - A two - phase three-phase transformer comprises two similar units 1, 1<1> the three phase windings 3, 3<1> of which are adapted to have parts connected in parallel or series to enable either unit to operate in either the " main " or " teaser " position whilst no part of the core is exposed to the ampere turns of the two phase winding only, The two phase windings 5, 5<1> each consist of two sections in parallel, and the three phase windings of each unit are provided with symmetrical voltage adjusting taps 8, 11, 8<1>, 11<1>.
