Книга "Electrical Installation Calculations. For Compliance with BS 7671:2008" является необходимым руководством для тех, кто работает в области электрических установок. В книге представлены инструменты, необходимые для проведения точных расчетов электрических схем. Авторы используют обширные примеры расчетов, что упрощает понимание материала и помогает читателям осуществлять необходимые проверки программного обеспечения для расчета размеров электрических кабелей. Книга также содержит информацию о различных типах кабелей, включая кабели с армированием и земляными петлями. Новые разделы посвящены зарытым кабелям, учитывающим теплопроводность почвы, и группировке кабелей в траншеях. Книга предназначена не только для электриков, но и для студентов и инженеров. Она является незаменимым ресурсом для тех, кто занимается проектированием, установкой и техническим обслуживанием электрических систем, а также для контрактных менеджеров и представителей промышленных предприятий.
Основная часть текста представляет собой машинно переведенный отрывок из английского описания книги "Электрические расчеты для соответствия BS 7671 : 2008" (Electrical Installation Calculations for Compliance with BS The book is intended as an essential reference and basic learning tool and as such it assumes no knowledge of electrical matters whatsoever, so that all readers will find their entry into the world of electrical calculation simple and straightforward. Employing a practical, case-study approach Jenkins starts off with a number of examples which demonstrate the actual method by which the calculations in question work. Through several worked examples the aims of each electrical calculation are gradually revealed. It then moves on to describe the different types of calculate that are needed in the context of electrical installations, including the creation of a report on cable size specification programmes and protective conductor sizes and circumstances. It also mentions how to identify the earth fault angular impedians while providing much knowledge about short-circuit prevention including defining conditions to create a thorough design of installation circuits, which is the unique feature of the book. Bearing in mind, every engineer will find Electrical Installation Calculatio to be an invaluable and simple tool for designing efficient electrical systems. Although it would not substitute the need for special software, which tries to autocorrect errors when designing or defining installations, it is appropriate as a supplement and facilitation for the user, saving them time and effort not only while establishing projects but also whilst calibrating their work. Despite being an introductory textbook, Jenkins Book has a solid quality and concise, however simplistically stated explanations offer the indisputable benefit of setting the foundation behind electrical works.

Описание книги от Jenkins B. D.
Manual calculations are still extensively used and in particular are necessary for checking and verifying various software calculation design packages. It is highly recommended that users of such software familiarise themselves with the rudiments of these calculations prior to using the software packages. This essential book fills the gap between software and manual calculations. It provides the reader with all the necessary tools to enable accurate calculations of circuit designs. Rather than complex equations, this book uses extensive worked examples to make understanding the calculations simpler. The focus on worked examples furnishes the reader with the knowledge to carry out the necessary checks to electrical cable sizing software programmes. Other key features include: Updated information on 230 volt references and voltage drop under normal load conditions New sections on buried cables that take into account soil thermal conductivity, trenches and grouping, allowing readers to carry out accurate cables sizing Information and examples of steel wired armour cables, new to this edition. This includes sufficiency during short circuits and, for cables with externally run CPCs, gives unique fault conditions. Covers calculations of cross-sectional areas of circuit live conductors Earth fault loop impedances Protective conductor cross-sectional areas and short circuit conditions Short circuit protection. The last chapter combines all of the calculations of the previous chapters to enable the reader to complete an accurate design of an installation circuit under all conditions. A unique tool for detailed electrical installation trade, Electrical Installation Calculations, Fourth Edition is invaluable to electricians, electrical designers, installers, technicians, contractors, and plant engineers. Senior electrical engineering students and technical colleges, junior engineers, and contracts managers will also find this text useful.
