Circuit breakers present very special design problems because of the wide mixture of experience required.</p><p xmlns="http://ns.editeur.org/onix/3.0/reference">Designers need to have an understanding of the parameters of power systems in which circuit breakers have a duty; of the physics of the arc produced during the interrupting process; of electrical engineering which is concerned with the insulation co-ordination and design problems; of mechanical engineering on which the performance and reliability of the operation of the circuit breaker depend; and of the need to meet cost-effective criteria.</p><p xmlns="http://ns.editeur.org/onix/3.0/reference">Perhaps because of the wide range of techniques involved, there has until now been very little co-ordinated information available in a form suitable for use at universities and for providing subsequent guidance for postgraduate purposes; and for engineers who are concerned with design, system engineering or the use of circuit-breakers, who may need to have, in varying degrees, an understanding of the design problems involved in circuit breakers.</p><p xmlns="http://ns.editeur.org/onix/3.0/reference">The approach in editing this book has been to invite eminent engineers concerned with circuit breakers to write chapters in areas that are of special interest to them. It has therefore been planned with chapters covering defined subjects. All of the authors are, or have recently been, occupying senior positions in the power circuit breaker industry.</p>Mon, 11 Jun 2018 23:50:48 GMThttps://shop.theiet.org:443/pwr-cct-breaker-theory-designhttps://shop.theiet.org:443/design-modern-cont-syst<p xmlns="http://ns.editeur.org/onix/3.0/reference">This book presents developments in analysis and design techniques for control systems. Included are exciting results for feedback systems using complex variable methods, the important concept of robustness in controller design and the increasingly important topic of decentralized control for large scale systems. These and many other contributions illustrate the great activity and rapid progress which has taken place in the subject over the past few years. Only by bringing these contributions together under one cover can the practising engineer in industry and indeed the engineer in university or polytechnic keep fully informed on the 'state of the art' on a number of different fronts. Application of the theoretical developments and practical aspects of the subject are not forgotten; analysis and design of a nuclear boiler and some direct digital control system design procedures are but two topics discussed in the present book. Several of the chapters are followed by problems on the subject matter and worked solutions to most of these problems are given at the end of the book. This aspect will find favour with many readers since such contributions are often a great help in the understanding of the subject matter.</p>Mon, 11 Jun 2018 21:14:14 GMThttps://shop.theiet.org:443/design-modern-cont-syst
