Abstract

563,731. Electricity supply. BRITISH THOMSON-HOUSTON CO., Ltd. March 22, 1943, No. 4605. Convention date, March 28, 1942. [Class 38 (iv)] Transformer arrangements.-To prevent heavy circulating currents in the windings of regulating transformers operating in parallel when switches 6, 6<SP>1</SP> varying the twin ratios do not operate simultaneously, a balancing reactor or autotransformer 11 is connected between the transformer windings and the common output or input conductor, such as 12, so that any circulating current may develop a voltage to limit it. The turn ratios may be adjustable manually or, as shown, automatically. When the transformers have unequal ratings, the parts of the windings 11 are suitably proportioned. The arrangement is described also in its application to three three-phase transformers in parallel : each reactor has three windings with a common terminal connected to one phase conductor and each of the other terminals is connected to that phase of one of each of the transformers ; a reactor may be connected in the input side of each of two phases and a third reactor in the output side of the remaining. phase.
