Preface:
This edition was updated by two of us, Greg Stone and Ian Culbert. Given the developments in rotating machine insulation in the past decade, readers will see expanded information on the effect of drives on insulation, the addition of a number of relatively new failure mechanisms, and new diagnostic tests. Many more photos of deteriorated insulation systems have been added in this edition. Many more references have been added, and recent changes in IEEE and IEC standards have been incorporated. We have also added descriptions of the insulation systems used by Chinese and Indian machine manufacturers. The information on Chinese systems came from Mr. Yamin Bai of North China EPRI. Mr. Bai and his colleagues were also responsible for the Chinese version of the first edition of this book. New appendices were added, which give detailed information on the insulation systems used by many manufacturers, as well as insulation material properties. These tables first appeared in a US Electric Power Research Institute (EPRI) document that is long out of print. However, given the number of machines still using these systems and materials, we thought it will be useful to include the information here. We again would like to thank our spouses, Judy and Anne, and also our employer, Iris Power L.P. We are also grateful to Ms. Resi Zarb for help in organizing and editing the second edition. Finally, we thank the readers of the first edition who took time to point out errors and omissions in the first edition.
Since electrical motors and generators were invented, a vast range of electrical machine types have been created. In many cases, different companies called the same type of machine or the same component by completely different names. Therefore, to avoid confusion, before a detailed description of motor and generator insulation systems can be given, it is prudent to identify and describe the types of electrical machines that are discussed in this book. The main components in a machine, as well as the winding subcomponents, are identified and their purposes described. Although this book concentrates on machines rated at 1 kW or more, much of the information on insulation system design, failure, and testing can be applied to smaller machines, linear motors, servomotors, etc. However, these latter machine types will not be discussed explicitly.
