We were on the lookout for ice. I was in a 32 foot sailing yacht with writer and explorer Tristan Gooley, undertaking a double-handed sail from Scotland through the Faroes up to 66 33 45.7 N and the midnight sun. Now sailing out of the Arctic Circle we were approaching Iceland from the north, heading for the Denmark Straits, where ice flowed south. The Admiralty Pilot warned of bergs but the ice charts we had sailed with were over a week old. We needed an update.

This book on electrostatic discharge phenomena is essentially a translation and update ofa Swedish edition from 1992. The book is intended for people working with electronic circuits and equipments, in application and development. All personnel should be aware of the ESD-hazards, especially those responsible for quality. ESD-prevention is a part of TQM (Total Quality Management). The book is also usable for courses on the subject.

Since the original publication of Manual 74 in 1991, and the preceding “Guidelines for Transmission Line Structural Loading” in 1984, the understanding of structural loadings on transmission line structures has broadened signifi cantly. However, improvements in computational capa- bility have enabled the transmission line engineer to more easily deter- mine structural loadings without properly understanding the parameters that affect these loads. Many seasoned professionals have expressed concern for the apparent lack of recent information on the topic of struc- tural loadings as new engineers enter this industry. The Committee on Electrical Transmission Structures is charged with the responsibility to report, evaluate, and provide loading requirements of transmission struc- tures. This task committee was therefore formed to update and revise the 1991 manual.

The first edition as well as its forerunner of Kuffel and Abdullah published in 1970 and their translations into Japanese and Chinese languages have enjoyed wide international acceptance as basic textbooks in teaching senior under- graduate and postgraduate courses in High-Voltage Engineering. Both texts have also been extensively used by practising engineers engaged in the design and operation of high-voltage equipment. Over the years the authors have received numerous comments from the text’s users with helpful suggestions for improvements. These have been incorporated in the present edition. Major revisions and expansion of several chapters have been made to update the continued progress and developments in high-voltage engineering over the past two decades.

Battery systems for energy storage are among the most relevant technologies of the 21 st century. They – in particular modern lithium-ion batteries (LIB) – are enablers for the market success of electric vehicles (EV) as well as for stationary energy storage solutions for balancing fluctuations in electricity grids resulting from the integrationofrenewableenergysourceswithvolatilesupply 1 .BothEVandstationary storage solutions are important because they foster the transition from the usage of fossil energy carriers towards cleaner renewable energy sources. Furthermore, EV cause less local air pollution and noise emissions compared to conventional combustion engine vehicles resulting in better air quality especially in urban areas. Unfortunately, to this day, various technological and economic challenges impede a broad application of batteries for EV as well as for large scale energy storage and load leveling in electricity grids.
