Abstract

381,109. Transformers &c. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and STEARN, G. F., 65, Lichfield Road, Stafford. April 16, 1932, No. 10968. [Class 38 (ii).] A tapped winding A, B, with means for tap-changing on load, is divided into two sections, a second or potentiometer winding 2 being connected between points G, H equidistant from the ends of the sections, while a tap-changing switch 3 is adapted to connect the inner end of one section of the winding to any one of a number of tappings on the other section. The invention may be applied to transformers or inductances, and is especially applicable to the secondary windings of three to six phase transformers for use with rectifying systems, the potentiometer windings being provided with tappings M which may be connected -together to form the star point of the six-phase system.
