newnes electrical power engineers handbook

[...]... this book is electrical power equipment, a change of title was agreed and so we now have the Newnes Electrical Power Engineer’s Handbook At the same time, some areas of the technology continue to advance apace, particularly in the structure and operation of power systems, and in emc and power quality So some chapters needed a substantial overhaul even though the Newnes Electrical Engineer’s Handbook was... finally, but perhaps most importantly, a chapter on health and safety has been added for this edition; this issue rightly pervades Newnes Electrical Power Engineer’s Handbook 3 most areas of the use of electrical power and this topic is a valuable addition to the handbook In most chapters there is a closing section on standards, which influence all aspects of design, specification, procurement and operation... Drive power circuits 10.10.1 DC motor drive systems 10.10.1.1 AC to dc power conversion 10.10.1.2 Single-converter drives 10.10.1.3 Dual-converter drives 10.10.1.4 Field control 10.10.1.5 DC to dc power conversion 10.10.2 AC motor drive systems 10.10.2.1 AC to ac power converters with intermediate dc link 10.10.2.2 General characteristics of a voltage source inverter 10.11 Effects of semiconductor power. .. neglecting the importance of electrical power systems and plant, and of underestimating the value of the skilled engineers necessary to support this infrastructure The major power failures of the past few years, in the Eastern seaboard of the USA, in Auckland, in Italy, in London and in parts of Scandinavia have highlighted how dependent a modern society is on a reliable source of electrical energy So, the... the major classes of electrical equipment operate In a handbook, it is not possible to set out a comprehensive treatment but the aim is to provide a balanced overview, and perhaps to engender the interest to pursue areas in more depth A more complete coverage of all the subjects addressed here can be found in the Newnes Electrical Engineer’s Reference Book The structure of the handbook is, as before,... number of applications in electrical engineering The following four chapters describe different groups of equipment which use or store electrical energy Probably the most important here is electric motors and drives, since these use almost two-thirds of all electrical energy generated Power electronics is of growing importance not only in the conversion and conditioning of power, most notably in variable-speed... was first asked to update the Newnes Electrical Engineer’s Handbook, it seemed a relatively straightforward task But after studying the reviewer’s comments which had been assembled by the publisher it became clear that a number of changes in emphasis would be worthwhile It was also evident that in North America, a clearer distinction has to be made between electrical power engineering and electronics...
