Available in PDF, EPUB and Kindle. Book excerpt: This book covers structural and foundation systems used in high-voltage transmission lines, conductors, insulators, hardware and component assembly. In most developing countries, the term “transmission structures” usually means lattice steel towers. The term actually includes a vast range of structural systems and configurations of various materials such as wood, steel, concrete and composites. This book discusses those systems along with associated topics such as structure functions and configurations, load cases for design, analysis techniques, structure and foundation modeling, design deliverables and latest advances in the field. In the foundations section, theories related to direct embedment, drilled shaf ts, spread foundations and anchors are discussed in detail. Featuring worked out design problems for students, the book is aimed at students, practicing engineers, researchers and academics. It contains beneficial information for those involved in the design and maintenance of transmission line structures and foundations. For those in academia, it will be an adequate text-book / design guide for graduate-level courses on the topic. Engineers and managers at utilities and electrical corporations will find the book a useful reference at work.

Book excerpt: Excerpt from Pole and Tower Lines: For Electric Power Transmission That this is no imaginary charge is substantiated by the history of transmission line construction. Until recent years the rule-of - thumb practices of telephone companies - worthy results of the test of time as many of them are - were followed blindly by those in charge of electrical transmission. As a result there are many improperly constructed lines and erroneous ideas prevail regarding the facts and principles involved in their design. This condition should no longer be allowed to exist. It is not the purpose of the writer to deal with purely electrical problems, such as the relation of voltage and size of the wires to the electrical characteristics of a line, or with such very specialized matters as the design of insulators. The problem is rather to develop a clearer preception of the application of the laws of mechanics to the case in hand. The writer wishes to acknowledge, with thanks, the assistance rendered by Mr. W. L. Cadwallader in preparing the tables and computations, and by those in charge of various properties in furnishing illustrations and data relating thereto.

This book was released on 2012 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Standard provides a uniform basis for the design, detailing, fabrication, testing, assembly, and erection of steel tubular structures for electrical transmission poles. These guidelines apply to cold-formed single- and multipole tubular steel structures that support overhead transmission lines. The design parameters are applicable to guyed and self-supporting structures using a variety of foundations, including concrete caissons, steel piling, and direct embedment. Standard ASCE/SEI 48-11 replaces the previous edition (ASCE/SEI 48-05) and revises some formulas that are based on other current industry standards. This Standard includes a detailed commentary and appendixes with explanatory and supplementary information. This Standard will be a primary reference for structural engineers and construction managers involved in designing and building electrical transmission lines, as well as engineers and others involved in the electric power transmission industry.

This book was released on 2012-11-25 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual vertically integrated utilities, is being used to move power between regions to support the needs of competitive markets for power generation. Primarily because of ambiguities introduced as a result of recent restricting the of the industry and cost pressures from consumers and regulators, investment to strengthen and upgrade the grid has lagged, with the result that many parts of the bulk high-voltage system are heavily stressed. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. Such an attack could be carried out by knowledgeable attackers with little risk of detection or interdiction. Further well-planned and coordinated attacks by terrorists could leave the electric power system in a large region of the country at least partially disabled for a very long time. Although there are many examples of terrorist and military attacks on power systems elsewhere in the world, at the time of this study international terrorists have shown limited interest in attacking the U.S. power grid. However, that should not be a basis for complacency. Because all parts of the economy, as well as human health and welfare, depend on electricity, the results could be devastating. Terrorism and the Electric Power Delivery System focuses on measures that could make the power delivery system less vulnerable to attacks, restore power faster after an attack, and make critical services less vulnerable while the delivery of conventional electric power has been disrupted.

This book was released on 1906 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical supply from transmitted water-power is now distributed in more than fifty cities of North America. These include Mexico City, with a population of 402,000; Buffalo and San Francisco, with 352,387 and 342,782 respectively; Montreal, with 266,826, and Los Angeles, St. Paul, and Minneapolis, with populations that range between 100,000 and 200,000 each. North and south these cities extend from Quebec to Anderson, and from Seattle to Mexico City. East and west the chain of cities includes Portland, Springfield, Albany, Buffalo, Hamilton, Toronto, St. Paul, Butte, Salt Lake City, and San Francisco. To reach these cities the water-power is electrically transmitted, in many cases dozens, in a number of cases scores, and in one case more than two hundred miles. In the East, Canada is the site of the longest transmission, that from Shawinigan Falls to Montreal, a distance of eighty-five miles.

Excerpt: ...brackets, riveted to the outer stiffeners of the bridge. This construction was considered advisable as the line had to cross two railroads, one heavy high-voltage line on tall towers, and several very important telephone and telegraph systems, and 1 Subsequently wrecked by a very severe sleet-storm. there was not enough space available between the existing power and telegraph systems. In making such attachments to bridges, and to some extent to any foreign structures, the construction must be accessible without interference with other interests, and at the same time be free from the probability of injury by foreign workmen. CHAPTER VIII CONCRETE POLES Wood poles had and still have certain advantages; they also have certain disadvantages. Some of the good points cannot be duplicated in concrete, but on the other hand, some of the objectionable features can be eliminated. Therefore, omitting undue enthusiasm on the one hand and any pretensions to magic excellence on the other, the matter is purely and simply one of final cost and final efficiency. It is self evident that concrete poles can be made, and it is fairly well known that a few thousand have been made and are now in service. The only remaining considerations seem to be ones of mechanical efficiency and actual or proper cost. The question of mechanical efficiency is in reality combined with that of cost. Given time-and money enough there are few structures which cannot be constructed, even by an amateur. Economical construction is another matter, and by economical is meant true economy--final economy--not merely reduced first cost. Thus, in the case of pole construction, we find that some have been built at a low initial cost but with an equally low mechanical efficiency, while...
