Differential protection is a fast and selective method of protection against short-circuits. It is applied in many variants for electrical machines, trans-formers, busbars, and electric lines. Initially this book covers the theory and fundamentals of analog and numerical differential protection. Current transformers are treated in detail including transient behaviour, impact on protection performance, and practical dimensioning. An extended chapter is dedicated to signal transmission for line protection, in particular, modern digital communication and GPS timing. The emphasis is then placed on the different variants of differential protection and their practical application illustrated by co...
How modern notions of architectural style were born—and the debates they sparked in nineteenth-century Germany. The term style has fallen spectacularly out of fashion in architectural circles. Once a conceptual key to understanding architecture’s inner workings, today style seems to be associated with superficiality, formalism, and obsolete periodization. But how did style—once defined by German sociologist Georg Simmel as a place where one is “no longer alone”—in architecture actually work? How was it used and what did it mean? In Style and Solitude, Mari Hvattum seeks to understand the apparent death of style, returning to its birthplace in the late eighteenth century, and char...
This second fully revised and extended edition of “Zoonoses - Infections Affecting Humans and Animals” covers the most important pathogens impacting both human and animal public health and debates current developments in this interdisciplinary field from a One Health perspective. Following a "setting" approach, the individual chapters each review zoonoses occurring in a specific group of animals, such as production animals, pets or wildlife, or in a defined ecosystem. A focus is put on zoonoses emerging along the food chain and on antibiotic resistance as an increasing challenge in infectious disease management. Special interest chapters debate non-resolved and currently hotly debated zo...
Hainsfarth is a small town next to Oettingen, located in Bavaria somewhat halfway between Augsburg and Nuremberg, not far from Nördlingen. At least since the 13th century, Jews lived in Hainsfarth, where they made up half of the population at times. There has been no Jewish community since 1940, but with the restored synagogue, the recently renovated Jewish school, remnants of a Mikveh and a largely preserved Jewish cemetery, Hainsfarth has a remarkable ensemble of architectural evidence of Jewish life and culture in southern Germany. The descendants of the Hainsfarth Jews produced scholars, actors and successful bankers. After all, two of the four teachers of the Jewish school were close relatives of later US Secretary of State Henry Kissinger. The booklet describes with numerous illustrations in short form history and institutions of the Jews of Hainsfarth.
When planning an industrial power supply plant, the specific requirements of the individual production process are decisive for the design and mode of operation of the network and for the selection and design and ratings of the operational equipment. Since the actual technical risks are often hidden in the profound and complex planning task, planning decisions should be taken after responsible and careful consideration because of their deep effects on supply quality and energy efficiency. This book is intended for engineers and technicians of the energy industry, industrial companies and planning departments. It provides basic technical network and plant knowledge on planning, installation a...

This book constitutes the refereed post-conference proceedings of the 13th TPC Technology Conference on Performance Evaluation and Benchmarking, TPCTC 2021, held in August 2021. The 9 papers presented were carefully reviewed and selected from numerous submissions. The TPC encourages researchers and industry experts to present and debate novel ideas and methodologies in performance evaluation, measurement, and characterization.
