Book excerpt: Excerpt from Hydroelectric Developments and Engineering: A Practical and Theoretical Treatise on the Development, Design, Construction, Equipment and Operation of Hydroelectric Transmission Plants Owing to our supposedly inexhaustible coal supply, interest in hydraulic development has naturally been of tardy growth until recent years; and it is only lately that the government has taken steps toward the development and commercial use of water power resources and the preservation of the forests. In Europe the limited coal supply early induced the utilization of the water resources; and the various Continental governments encouraged this movement by granting favorable franchises, and in many cases advanced money to finance the undertakings, at the same time protecting the water-sheds by rigid enforcement of forest preservation laws. It is but natural, therefore, that hydraulic developments and electric transmission received early and special attention abroad, and as a result Europe abounds in hydraulic developments, utilizing heads varying from 16.5 inches to 3116 feet. Believing that the progress in hydroelectric engineering is stimulated by the interchange of American and European ideas, and having had considerable practical experience, both here and abroad, the author presents this volume as comprehending the most advanced American and European practice, and trusts that numerous novel features of hydraulic, mechanical, and electrical engineering are made obvious. To point out a few of the new features, the following are cited: Air-shafts and equalizing chambers in connection with pressure tunnels. Seamless-welded, flangeless, telescoping penstocks to facilitate shipment and to eliminate expansion joints. Siphon system, in contradistinction to the inverted siphon - which latter is a misnomer. Impulse wheels with draft tubes and multiple, non-water-wasting nozzles. Compound turbine on a single shaft, the discharge of one being the supply of the other. Rapid and complete turbine tests by curtain methods and autographic recording device. Thirty-thousand-volt generators and their efficient protective devices against lightning. Unique combination of single and three-phase high-tension transmission systems from three-phase generators. Wagon-panel switchboard systems. Segregation and decentralization of switchboards. Continuous water-flow grounders and horngaps with micrometric setting. Two-legged transmission towers and line-crossing protection.
