This book was released on 2016-01-07 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The successful transmission of electrical power beneath the surface of the earth depends on a number of factors including ambient temperature, sheath bonding, cable laying depth, and especially the formation of dry zones around underground cables. Environmental Impacts on Underground Power Distribution studies the factors which affect the maximum current rating of subterranean power cables as well as various methods to maximize electrical current transmission. Focusing on the latest tools, methodologies, and research in the field, this publication is designed for use by electrical engineers, academicians, researchers, and upper-level students.

This book was released on 2016-10-24 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thesis (M.A.) from the year 2015 in the subject Electrotechnology, grade: -, Warsaw University of Technology (Electrical Engineering), language: English, abstract: This study is focused on installations and faults diagnosis of high voltage underground cables and examined on the various ways through which they can be identified and corrected. It has been found that wear and tear is one of the major issues leading to electric faults like power loss. There has been seen that several causes of failure which could be identified with them and analyze better ways of detecting them. So, it has been looked at how to detect degradation of insulation of the underground cable. After a thorough analysis of fault detection techniques have been explained, the pre-location fault techniques is described; I illustrated many methods which aid to discover the fault location. I also developed a method which contributes in pre-location of the fault based on Matlab simulation and mathematical slope equation. This method was invented after the observation that the voltages measured at the local and remote substations, after filtering and after Fourier analysis, showed a linear behavior that was proportional to the respective distances between the fault location and the mentioned substations or generators. Thus, the developed method exploits such a linearity to estimate the fault location by interpolation, assuming that the parameters of the line are previously known and that dedicated devices are located on site in both substations to provide post-fault measurements of the faulted line. Finally, I clarify many pin-pointing methods to precisely determine the fault location.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of a Department of Energy-sponsored workshop in the installation of underground power transmission cables are reported. The workshop was held in Pittsburgh, Pennsylvania, October 2--5, 1978. Sixty-two participants, representing equipment manufacturers, utilities, contractors, universities, and government agencies, were divided into topic groups covering specific installation activities. Discussion was directed toward a review of the state of the art in underground cable installation, future equipment and technique development requirements, and the formulation of conclusions and recommendations. The principal technological problem for underground installation is the lack of ability to locate underground obstacles, principally in urban and suburban areas. Development of a sensing system to locate obstacles was given a high priority by nearly all topic groups. The lack of market definition was seen as the principal impediment to competition and development of specialized equipment. Most participants felt that the federal government must assume a role in research and development of new equipment and techniques. However, the participants did not favor increased federal regulation of underground cable installation systems.

Available in PDF, EPUB and Kindle. Book excerpt: This text covers the computation of current ratings of electric power cables, a procedure essential in the determination of the maximum current a power cable can carry without overheating. It also helps engineers determine the cable size and type in order to prevent the need for re-installation.

Download or read book Submarine Power Cables written by Thomas Worzyk and published by Springer Science & Business Media. This book was released on 2009-08-11 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for high-performance submarine power cables is increasing as more and more offshore wind parks are installed, and the national electric grids are interconnected. Submarine power cables are installed for the highest voltages and power to transport electric energy under the sea between islands, countries and even continents. The installation and operation of submarine power cables is much different from land cables. Still, in most textbooks on electrical power systems, information on submarine cables is scarce. This book is closing the gap. Different species of submarine power cables and their application are explained. Students and electric engineers learn on the electric and mechanic properties of submarine cables. Project developers and utility managers will gain useful information on the necessary marine activities such as pre-laying survey, cable lay vessels, guard boats etc., for the submarine cable installation and repair. Investors and decision makers will find an overview on environmental aspects of submarine power cables. A comprehensive reference list is given for those who want further reading.

Download or read book Underground Cable Thermal Backfill written by S.A. Boggs and published by Elsevier. This book was released on 2013-10-22 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground Cable Thermal Backfill documents the proceedings of the ""Symposium on Underground Cable Thermal Backfill,"" held in Toronto, Canada, 17-18 September 1981. The symposium brought together research, design, and installation engineers from utilities, cable manufacturers, and universities to present and discuss developments in the field. The contributions of researchers at the symposium are organized into five chapters. Chapter 1 presents an overview of the state-of-the-art of cable backfill materials and soil thermal property measurements. The papers in Chapter 2 deal with developments in cable backfill materials. These include materials stabilized with moisture substitutes, pumpable materials, and materials stabilized with bound water. Chapter 3 covers thermal property measurements of soils and backfills. Through the automation of measurements and analysis using microprocessor based instruments and better control of experimental conditions, substantial improvements have been made in the area of measurement technology. Chapter 4 reports developments in the study of soil thermal stability and the implication thereof for thermal cable design. Chapter 5 discusses various aspects of thermal cable design, including methods for incorporating historical weather records to predict worst case soil and backfill thermal conductivities. This volume should serve as a useful introduction to the subject of cable thermal design for engineers involved in underground transmission and distribution systems.
