PREFACE. THE literature dealing with Central Station practice is, at the present time, exceedingly limited, but that relating to many of its branches is altogether as extensive and complete, notably that dealing with the steam engine, the dynamo machine, steam boilers, and many other subjects. At least as exhaustive in treatment are the text-books dealing with the abstract sciences underlying these machines and appliances, as thermodynamics, mechanics, electrical theory. A complete treatise on Central Station work would involve the production of a whole library of many volumes, for no field of engineering practice involves more varied and numerous branches of science, pure and applied, and to attempt to cover adequately in a single book the whole of the ground necessary for the complete exposition of the subject would be a task as futile as it would be absurd to undertake. Recognising these facts, the Author has attempted in the present work to describe those problems which arise in the practical operation of Central Stations, whether of a scientific, an engineering, or a commercial nature, and to indicate the solution which his own experience, or that of other engineers similarly placed, has dictated. He has endeavoured to avoid more than a reference to those matters which can be found so fully and so ably treated in existing text-books and treatises, and to elaborate and treat fully those subjects which, though perhaps familiar to Central Station engineers, are not, to his knowledge, to be found. readily, if at all, in any book. This will explain what might otherwise be considered the want of due proportion in the amount of space devoted to the various items considered with reference to their relative importance. For example, more attention may be given to the details of the jointing 95996 |
