Condition monitoring of engineering plant has increased in importance as engineering processes are automated and manpower is reduced. However, electrical machinery receives attention only at infrequent intervals when plant is shut down and the application of protective relays to machines has also reduced operator surveillance.A first edition of Condition Monitoring of Electrical Machines, written by Tavner and Penman, was published in 1987. The economics of industry have now changed, as a result of the privatisation and deregulation of the energy industry, placing emphasis on the importance of reliable operation of plant, throughout the whole life cycle, regardless of first cost. The availability of advanced electronics and software in powerful instrumentation, computers, and digital signal processors (DSP) has simplified our ability to instrument and analyse machinery. As a result condition monitoring is now being applied to a wider range of systems, from fault-tolerant drives of a few hundred watts in the aerospace industry, to machinery of a few hundred megawatts in major capital plant.In this new book the original authors have been joined by Ran, an expert in power electronics and control, and Sedding, an expert in the monitoring of electrical insulation systems. Together the authors have revised and expanded the earlier book, merging their own experience with that of machine analysts to bring it up to date. The book is aimed at professional engineers in the energy, process engineering and manufacturing industries, plus research workers and students.

Semiconductor power switches are essential to the operation of power electronic converters and systems. Traditional silicon-based semiconductor power switches have intrinsic physical limits to their performance. Wide Bandgap (WBG) devices deliver higher efficiency, smaller size, and/or lighter weight. Applications in power grid electronics as well as in electromobility are on the rise, but WBG devices also pose new challenges, in particular due to their fast switching speed and the need for protection.SiC Power Devices and Applications covers the progress made in the area of WBG technologies, with a particular focus on silicon carbide, and a strong emphasis on their applications. Following an introduction to the topic, chapters cover fabrication and packaging, applications in data centres and telecom, motors and generators, transport and drives, avionics, power grids and HVDC, PV and energy storage, and in wind turbine converters. The book systematically and thoroughly addresses the important aspects of real-life applications of WBG devices.The book is important reading for researchers and engineers in academia and industry, especially those involved in R&D of state-of-the-art power electronics, as well as advanced students in power electronics and semiconductor science.
