Electricity Considered In Its Application To Motive Power PDF Download

Excerpt from Electric Motive Power: The Transmission the Distribution of Electric Power by Continuous by Alternate Currents, With a Section on the Applications of Electricity to Mining Work "Electric Motive Power" is designed to be a practical treatise for Mechanical and Mining Engineers and other Students of Applied Electricity. Taking for granted an elementary knowledge of the theory of Electricity and Magnetism, I have endeavoured to give a clear exposition of the principles governing Electric Transmission of Power, and to develop them in accordance with the best practice of the present time. In doing this I have deemed it advisable to discuss the design of Dynamos, Alternate and Continuous Current Motors, Alternators and Transformers, as well as the various systems in vogue for transmitting and distributing power. A large part of the book is devoted to a careful consideration of the alternate current systems, both single and polyphase. This is necessitated by their growing importance, as it is now well recognised by the leading electrical engineers of Europe and America that for power transmission they are superior to continuous -current systems. In a short Appendix are given some figures with reference to the prime cost of plants for long-distance transmission. The last two Chapters deal exhaustively with the applications of electricity to mining work, particularly with reference to collieries and coal-getting. It is hoped they will prove to be of interest to the large number of Mining Engineers who are now using or are advising the use of electric plants for lighting and power purposes.
