About the Book

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 Excerpt: ...on one four-wire system of distribution; and to operate independent systems in parallel circuit on said four-wire system. Three single-phase transformers are used. The primary windings are connected in delta, and the secondary windings are also connected in delta. A distribution line, 7, tapped at the middle of the secondary winding, 2a; a distribution line, 8, tapped at----per cent, of the length from one end of the winding, 3a; a distribution line, Q, tapped on the connection between the end windings, 2a and 3a; a distribution line, 10, tapped at----per cent. of the length from the end of wind ing la, and translating means connected on said distribution lines both for two-and three-phase on. At la, 2a and 3a are the secondary windings of said transformers. The secondary winding, la, is tapped at D, which is about 86.6 per cent, of its length, by the line, 10; which serves also as a leg for both the two-and three-phase circuits. The secondary winding, 2a, is tapped at its central point A, by a line, 7; forming one leg of the two-phase circuit. The secondary winding, 3a, is tapped at approximately 86.6 per cent. of its length from one end, at about the point, B, by a line, 8, to serve as one leg of both the three-and two-phase circuits. C represents the point of a tap taken from the junction of two secondary windings which are shown connected in the series circuit, which serves as another leg for both twoand three-phase circuits. The arrangement accomplishes the operating of synchronous and non-synchronous apparatus of two-phase and three-phase design without the aid of transformers or split-phase devices. The operation consists in generating three-phase alternating currents in the lines, 4, 5 and 6, transforming the same into three-phase currents in the le...
