Abstract

25,785. Parsons, C. A., and Law, A. H. Nov. 8. Drawings to Specification. Exciting.-The voltage of alternating - current machines is regulated by the use of a small auxiliary exciter operating on, or in conjunction with, tho main exciter, and provided with one or more leakage paths, which are supplied with a current proportional to the main alternator current, for example as described in Specifications 24,141/05 and 13,712/07. In one arrangement, the main exciter is shunt-wound, and has additional fieldmagnet coils energized by the small exciter, whereby the main exciter can be designed with a practically straight characteristic curve. The auxiliary exciter may energize all the coils of the exciter ; or it may be connected directly in the main-field circuit of the alternator or in the shuntfieJd circuit of the exciter, so as to operate as a booster. The windings on the leakage paths may either be in the main circuit of the alternator, or may be arranged as a shunt to a resistance or inductance ; or they may be supplied by current transformers. In the case of polyphase machines, the leakage paths may be operated from one phase only.
