Overhead Distribution Lines

The only book containing a complete treatment on the construction of electric power lines. Reflecting the changing economic and technical environment of the industry, this publication introduces beginners to the full range of relevant topics of line design and implementation.

A general overview of the use of utility distribution poles, including for electric supply and communications applications Overhead Distribution Lines: Design and Applications provides information on the design and use of power and communication distribution lines. An excellent resource for those in the power and communication utilities industry, this book presents information on the physical characteristics of utility poles, overhead supply and communication cables, installation practices, joint-usage issues, and safety rules, including the National Electrical Safety Code (NESC), California-specific rules, and others. It describes how to select the proper poles for specific applications. The especially valuable final chapter provides examples showing how it all works in practice, providing a background allowing more effective use of related industry software. Rather than delving into detailed design and installation techniques, this book serves as an overview for engineers and non-technical audiences alike. At the same time, it serves as a compendium of technical information not readily available elsewhere. This unique book: Offers an overview of pole structures, pole installation and maintenance, wires and cables, and cable installation and maintenance—with examples Provides information on national standards documents such as the National Electrical Safety Code (NESC), ANSI O5.1, California General Order 95, and more Explores the "sag–tension" relationship between wires and poles Includes appendices that cover properties of messenger strands, wireless attachments, solution of equations to determine sag, under uniform and point loads Overhead Distribution Lines: Design and Applications offers readers an understanding of the basic principles and various issues related to electric supply and communications distribution lines. It is a valuable resource for utility engineers, as well as those without a technical background.

Overhead power lines are the only way to electrify many communities. Massive experience has been gained with electrification projects that can be used world-wide. This work presents the technology of overhead power lines, including sag, insulators, conductors, lightning, and grounding.

Complete coverage of power line design and implementation "This text provides the essential fundamentals of transmission line design. It is a good blend of fundamental theory with practical design guidelines for overhead transmission lines, providing the basic groundwork for students as well as practicing power engineers, with material generally not found in one convenient book." IEEE Electrical Insultation Magazine Electrical Design of Overhead Power Transmission Lines discusses everything electrical engineering students and practicing engineers need to know to effectively design overhead power lines. Cowritten by experts in power engineering, this detailed guide addresses component selection and design, current IEEE standards, load-flow analysis, power system stability, statistical risk management of weather-related overhead line failures, insulation, thermal rating, and other essential topics. Clear learning objectives and worked examples that apply theoretical results to real-world problems are included in this practical resource. Electrical Design of Overhead Power Transmission Lines covers: AC circuits and sequence circuits of power networks Matrix methods in AC power system analysis Overhead transmission line parameters Modeling of transmission lines AC power-flow analysis using iterative methods Symmetrical and unsymmetrical faults Control of voltage and power flow Stability in AC networks High-voltage direct current (HVDC) transmission Corona and electric field effects of transmission lines Lightning performance of transmission lines Coordination of transmission line insulation Ampacity of overhead line conductors

This book provides readers with up-to-date coverage of fault location algorithms in transmission and distribution networks. The algorithms will help readers track down the exact location of a fault in the shortest possible time. Furthermore, voltage and current waveforms recorded by digital relays, digital fault recorders, and other intelligent electronic devices contain a wealth of information. Knowledge gained from analysing the fault data can help system operators understand what happened, why it happened and how it can be prevented from happening again. The book will help readers convert such raw data into useful information and improve power system performance and reliability.

Electric Power Transmission and Distribution is a comprehensive text, designed for undergraduate courses in power systems and transmission and distribution. A part of the electrical engineering curriculum, this book is designed to meet the requirements of students taking elementary courses in electric power transmission and distribution. Written in a simple, easy-to-understand manner, this book introduces the reader to electrical, mechanical and economic aspects of the design and construction of electric power transmission and distribution systems.

The definitive guide to distribution and transmission line technology--fully updated Completely revised to reflect the 2012 National Electrical Safety Code (NESC), The Lineman's and Cableman's Handbook, 12th Edition, provides in-depth information on overhead and underground distribution and transmission lines. The latest OSHA, ANSI, and ASTM standards are emphasized throughout. This authoritative resource presents basic principles, equipment, standards, and safety regulations, allowing electrical workers to avoid costly errors, diagnose and repair power failures, and ensure optimum safety. A wealth of illustrations and photographs make it easy to understand the material, and self-test questions and exercises help reinforce key concepts. Comprehensive coverage includes: Electrical principles and systems * Substations * Circuits * Construction * Wood-pole, aluminum, concrete, fiberglass, and steel structures * Distribution automation * Emergency system restoration * Unloading, hauling, erecting, setting, and guying poles * Insulators, crossarms, and conductor supports * Line conductors * Distribution transformers * Lightning and surge protection * Fuses * Switches, sectionalizers, and reclosers * Voltage regulators * Transmission tower erection * Stringing, sagging, and joining line conductors * Live-line maintenance * Grounding * Street lighting * Underground distribution * Vegetation management * Distribution transformer installation * Electrical drawing symbols * Single-line and schematic diagrams * Voltage regulation * Units of measurement, electrical definitions, electrical formulas, and calculations * Maintenance of transmission and distribution lines * Rope, knots, splices, and gear * Climbing and wood poles * Protective equipment * OSHA 1910.269 * Resuscitation * Pole-top and bucket rescue
