Abstract
A PAPER by V. Easton (J. Inst. JSlec. Eng., 90, Pt. 2, No. 16 ; August 1943) deals with some of the factors which affect alternator design. Due to the rapid growth of interconnexions on many systems during the last fifteen years, the greatly increased voltage and current likely to be caused by a fault at many switching stations has necessitated the design of circuit-breakers of larger capacity, and in turn this has made desirable improved facilities for technical investigations and for proving the rating of the breakers. The paper discusses the mechanical and electrical factors which affect the design of alternators supplying power for switchgear testing, and a review is made of several methods of increasing the output of such alternators, the merits of each being critically examined.
