The classic reference for power-system engineers Power System Stability, Volumes I, II, III is a classic reference for power-system engineers, now reissued together as a set. Volume I, Elements of Stability Calculations, covers the elements of stability, principal affecting factors, and applications on power systems. Volume II, Power Circuit Breakers and Protective Relays features in-depth information on organization, materials, actions, and conditions as they relate to power system stability. Volume III, Synchronous Machines, details the more advanced calculations required in special circumstances that demand a higher level of accuracy than the simplified calculations presented in Volume I can provide.

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.

Although it is popularly assumed that the history of computing before the second half of the 20th century was unimportant, in fact the Industrial Revolution was made possible and even sustained by a parallel revolution in computing technology. An examination and historiographical assessment of key developments helps to show how the era of modern electronic computing proceeded from a continual computing revolution that had arisen during the mechanical and the electrical ages. This unique volume introduces the history of computing during the “first” (steam) and “second” (electricity) segments of the Industrial Revolution, revealing how this history was pivotal to the emergence of electronic computing and what many historians see as signifying a shift to a post-industrial society. It delves into critical developments before the electronic era, focusing on those of the mechanical era (from the emergence of the steam engine to that of the electric power network) and the electrical era (from the emergence of the electric power network to that of electronic computing). In so doing, it provides due attention to the demarcations between—and associated classifications of—artifacts for calculation during these respective eras. In turn, it emphasizes the history of comparisons between these artifacts. Topics and Features: motivates exposition through a firm historiographical argument of important developments explores the history of the slide rule and its use in the context of electrification examines the roles of analyzers, graphs, and a whole range of computing artifacts hitherto placed under the allegedly inferior class of analog computers shows how the analog and the digital are really inseparable, with perceptions thereof depending on either a full or a restricted view of the computing process investigates socially situated comparisons of computing history, including the effects of a political economy of computing (one that takes into account cost and ownership of computing artifacts) assesses concealment of analog-machine labor through encasement (“black-boxing”) Historians of computing, as well as those of technology and science (especially, energy), will find this well-argued and presented history of calculation and computation in the mechanical and electrical eras an indispensable resource. The work is a natural textbook companion for history of computing courses, and will also appeal to the broader readership of curious computer scientists and engineers, as well as those who generally just have a yearn to learn the contextual background to the current digital age. "In this fascinating, original work, Tympas indispensably intertwines the histories of analog and digital computing, showing them to be inseparable from the evolution of social and economic conditions.

Fully updated, Electrical Power Cable Engineering, Third Edition again concentrates on the remarkably complex design, application, and preparation methods required to terminate and splice cables. This latest addition to the CRC Press Power Engineering series covers cutting-edge methods for design, manufacture, installation, operation, and maintenance of reliable power cable systems. It is based largely on feedback from experienced university lecturers who have taught courses on these very concepts. The book emphasizes methods to optimize vital design and installation of power cables used in the interrelated fields of electrical, mechanical, and, to some extent, civil engineering. An in-depth exploration of power cable characteristics and applications, it illustrates the many factors that can hinder real-world cable performance. Content focuses on low and medium voltages, considering that these are used for the majority of cables in service globally. This edition also details techniques for testing shielded power cable systems in the field, demonstrating how conductor material size and design depend on ampacity, voltage regulation, and other factors. Covering everything from manufacturing to testing, this resource will benefit: Cable engineers and technicians (working for investor-owned utilities, rural electric cooperatives, and industrial manufacturers) who need to improve their oversight and understanding of power cables Universities that offer electrical power courses Professionals who must master new power cable terminology, engineering characteristics, and background information that will aid them in their decision making responsibilities The author is a life fellow of the IEEE and one of the original developers of industry standards for cables and accessories. To simplify field fundamentals and techniques for less experienced readers, his book contains new, updated, and expanded chapters and an extensive glossary, in addition to useful references, tables, equations, and photographs. More experienced engineers will appreciate the book’s invaluable updates on the emerging materials, products, and concepts driving their dynamic field.

Addressed to electrical engineers and others concerned with safe, cost-effective power cable design and installation, Anders (Ontario Hydro Technologies) shares his experience through examples in selecting optimal cable ratings, equations used in the selection process, model calculation sheets, and theoretical considerations. The volume is organized around thermal modeling (cable construction, installations, circuit theory, heat transfer and rating equations); evaluation of parameters (dielectric losses, joule losses, thermal resistances and capacitances); and advanced topics (special cable installations, ampacity computations, and economic selection of conductor cross section). Appendixes on related topics; list of symbols used, and table of US cable sizes. Annotation copyrighted by Book News, Inc., Portland, OR
