Gaseous Dielectrics II


Book Description

Gaseous Dielectrics II focuses on the discussion of the progress and issues related with gaseous dielectrics, their efficient use by the electric power industry, and how they affect the environment. This book features contributors who have pursued extensive research on gaseous dielectrics. The discussion starts with a presentation of the fundamental physics covering the subject. In this regard, numerical analyses are presented to show the nature of gaseous dielectrics. This book then proceeds by presenting the fundamental mechanisms involving corona discharge and breakdown in air as well as discharge processes in SF6. Supporting the discussion are numerical calculations that show how the processes progress. A discussion of “new gaseous dielectrics is also presented. In this consideration, the breakdown behavior of new gases and gas mixtures as well as their strength are elaborated. This topic is followed by the evaluation of the effect of surface defects on the breakdown of gases and gas mixtures. Another part of the book discusses the effects of conducting particles to gases and gas mixtures in gas-insulated systems. A discussion of the decomposition of gases and gas mixtures is presented, including high-voltage testing of gases and gas mixtures. The bioenvironmental effects of dielectric gases are also discussed. This selection is a valuable source of information for readers who are interested in studying the industrial utilization of gaseous dielectrics.




High Voltage and Electrical Insulation Engineering


Book Description

The book is written for students as well as for teachers and researchers in the field of High Voltage and Insulation Engineering. It is based on the advance level courses conducted at TU Dresden, Germany and Indian Institute of Technology Kanpur, India. The book has a novel approach describing the fundamental concept of field dependent behavior of dielectrics subjected to high voltage. There is no other book in the field of high voltage engineering following this new approach in describing the behavior of dielectrics. The contents begin with the description of fundamental terminology in the subject of high voltage engineering. It is followed by the classification of electric fields and the techniques of field estimation. Performance of gaseous, liquid and solid dielectrics under different field conditions is described in the subsequent chapters. Separate chapters on vacuum as insulation and the lightning phenomenon are included.

Environmental Compatible Circuit Breaker Technologies


Book Description

Recent research and development in the field of high-current circuit breaker technology are devoted to meeting two challenges: the environmental compatibility and new demands on electrical grids caused by the increasing use of renewable energies. Electric arcs in gases or a vacuum are the key component in the technology at present and will play a key role also in future concepts, e.g., for hybrid and fast switching required for high-voltage direct-current (HVDC) transmission systems. In addition, the replacement of the environmentally harmful SF6 in gas breakers and gas-insulated switchgear is an actual issue. This Special Issue comprises eight peer-reviewed papers, which address recent studies of switching arcs and electrical insulation at high and medium voltage. Three papers consider issues of the replacement of the environmentally harmful SF6 by CO2 in high-voltage gas circuit breakers. One paper deals with fast switching in air with relevance for hybrid fault current limiters and hybrid HVDC interrupters. The other four papers illustrate actual research on vacuum current breakers as an additional option for environmentally compatible switchgear; fundamental studies of the vacuum arc ignition, as well as concepts for the use of vacuum arcs for DC interruption.
