High voltage engineering is not only a key technology for a safe, economic and sustainable electric power supply. Furthermore, a broad spectrum of applications includes most of the innovative fields in engineering and science, such as medical engineering, laser technology, industrial production, automotive engineering, food technology, bioengineering, nanotechnology, environmental protection, recycling, electromagnetic compatibility, scientific research or superconductivity. "High Voltage Engineering: Fundamentals – Technologies – Applications" is based on the 3rd edition of the leading German standard work "Hochspannungstechnik", which is both a textbook for students and a reference book for engineers. It provides a unique and successful combination of scientific foundations, basic principles, modern technologies and practical applications, clearly illustrated by many figures, examples and exercises. It is considered that new challenges for high voltage engineering are brought about by emerging technologies and global development of economies and electricity supply infrastructure, especially in the fast developing countries.
