Abstract: 377,318. Automatic regulation; transformers. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Thompson, L. W.; 53, Baker Avenue, Schenectady, New York, Boyajian, A. ; 6, Maplewood Avenue; Blieux, E. V. de ; 64, Kenwood Avenue, both in Pittsfield, Massachusetts, and Case, B. A.; 1012, West Wayne Street, Fort Wayne, Indiana, all in U.S.A.) April 29, 1931, No. 12647. Convention date, April 29, 1930. [Classes 38 (ii) and 38 (iv).] Systems depending on static transformers.-The voltage of an A.C. load circuit 5 is regulated by a booster transformer 9, 10 having a saturable reactor 11 arranged so that variation of the saturation in accordance with current variations in the circuit 5 varies the boosting effect of the transformer. The reactor has a saturated winding 14 in series with a rectifier 15. In one form the saturating winding is connected through rectifiers in series with the shunt wind. ing of the transformer and condensers are connected in shunt with the said winding, with the reactor and across the series connection of transformer shunt winding and rectifier. Means associated with the reactor and assisting to saturate it, such as coils 20, 21, 42 in the load circuit, may neutralize the no-load boost of the transformer. A saturating winding 31 may be added to the transformer and supplied by rectified current proportional to the supply circuit voltage to reduce the no-load boost, and tend to compensate changes in the supply circuit voltage, and a second saturating winding 34 energized in proportion to the load current may also be added to the transformer. The saturable reactor may have a winding 42 connected in the load circuit to produce a bucking voltage. The series winding 43 of the booster transformer may be energized by the booster transformer shunt winding 10 and by the A.C. winding 41 of the reactor so that a boost or a buck is produced in the load circuit according to conditions. Various forms of saturable reactor are described. In all forms the windings are arranged to avoid inducing an A.C. voltage in the D.C. winding and the production of even harmonics through unequal distortion of the halves of the A.C. wave. Fig. 1 shows one arrangement of the windings on a three limbed core, Fig. 3, on a four limbed core. In a modification each A.C. winding is in the centre limb of a separate three-limbed core with which limb the D.C. winding is also interlinked, and in another the two A.C. windings are on the central limb of a four limbed core, the D.C. winding is interlinked with both and the outer links each include an air gap. The combined reactance and transformer shown in Fig. 7 has two cores each wound with a D.C. winding 14, 141, both cores threading the reactance coil 41 and transformer or bucking winding 42.
