methods of connectingtransformers on a two-phase system, using three line wires.In this case, the central wire acts as a common return, andthe voltage between the outside wires is 1.414 times that ofeach phase. The same remarks apply here as in the previ-ous case, and the three-wire arrangement… … § 14 ELECTRIC TRANSMISSION. 69 TRANSFORMERS OjNT THREE-PHASE CIRCUITS. 81. It is customary in America to use three single-phasetransformers for transforming from one pressure to anotheron three-phase circuits. In Europe, three-phase trans-formers are used in which there are three primary coils…
