Electrical Engineering, the Theory and Characteristics of Electrical Circuits and Machinery (Classic Reprint)

The more important additions include sections on complex alternating waves and wave analysis, on polyphase alternating current circuits, on the construction of the characteristic curves of direct-current generators and motors, on the design of directand alternating-current machinery, on theB londel diagram for the synchronous motor, on the symbolic method of analysis of the induction motor, on alternating-current commutator motors, and finally a chapter on electrical measuring instruments. The chapter on direct-current machinery has been entirely rewritten and much enlarged, and to make it complete a short chapter outlining the design of a direct-current generator has been added. This chapter and the other sections dealing with design are not intended to cover the work required in a course on design but only to give the student some idea of the formulae and constants involved. The chapter on measuring instruments has been placed at the end of the book because some of the principles involved cannot be well understood by the student until he has mastered the theory of the more important electrical machines. It was originally intended to introduce problems at the end of each chapter to be worked out by the student and also to give a list of references to the most important articles covering the subject matter of the chapter, but there was danger of making the volume too cumbersome. A number of good books of problems have been published recently and the student will find good lists of references at the ends of the various sections in theS tandard Handbook. My thanks are due to those teachers who have offered valuable criticisms of the arrangement and method of treatment in the first edition. ,CLARENCE V. CHRISTIE.
