Book excerpt: Excerpt from Electricity Meters: A Treatise on the General Principles, Construction, and Testing of Continuous Current and Alternating Current Meters Although the electricity meter forms the most important link in the chain connecting the supply station with the consumer, comparatively little has been written on the subject in this country. It is, therefore, hoped that the present work may supply what is wanting in this respect, and that some original matter may be found in the same, especially in connection with the limitations of three-wire meters, of single-phase meters for polyphase circuits, and the results obtained with polyphase meters incorrectly installed. For the sake of convenience, the meters described in this book are divided into three main classes - viz, Continuous current, Induction, and Tariff meters - arranged in eight chapters, corresponding to the following eight subdivisions: - Continuous current quantity meters: Continuous current energy motor meters (without iron in the field or armature): Continuous current energy meters of different types: Continuous current meters for special purposes (battery, switchboard, and tram-car meters): Single-phase and polyphase induction meters: Tariff and prepayment meters. The general principles involved are explained in three separate chapters, which precede the descriptions of the meters belonging to the three main classes as stated above. As the proper working of a meter depends on its mechanical as well as its electrical design, a special chapter is added in which the more important mechanical features of meter construction are pointed out, only the electrical details being given in the actual descriptions of the various types. A chapter on Testing, and an introductory chapter containing a few remarks relating to meters in general, are also included. After careful consideration, it was not deemed necessary to include an historical survey of the evolution of the electricity meter. The general design of electricity meters is at the present day fairly well established, the improvements being more a matter of detail and mainly of a mechanical nature, so that no purpose is served by giving descriptions of obsolete forms of meters, however ingenious their construction and interesting from a purely historical standpoint. With the exception of those meters which form the basis of present-day practice, the designs were on lines which are no longer followed. The main difficulty in writing a book of this description is the well-nigh impossibility of keeping absolutely up to date.
