Vacuum circuit breakers are widely used in distribution power systems for their advantages such as maintenance free and eco-friendly. Nowadays, most circuit breakers used at transmission voltage level are SF6 circuit breakers, but the SF6 they emit is one of the six greenhouse gases defined in Kyoto Protocol. Therefore, the development of transmission voltage level vacuum circuit breaker can help the environment. The switching arc phenomena in transmission voltage level vacuum circuit breakers are key issues to explore. This book focuses on the high-current vacuum arcs phenomena at transmission voltage level, especially on the anode spot phenomena, which significantly influence the success or failure of the short circuit current interruption. Then, it addresses the dielectric recovery property in current interruption. Next it explains how to determine the closing/opening displacement curve of transmission voltage level vacuum circuit breakers based on the vacuum arc phenomena. After that, it explains how to determine key design parameters for vacuum interrupters and vacuum circuit breakers at transmission voltage level. At the end, the most challenging issue for vacuum circuit breakers, capacitive switching in vacuum, is addressed. The contents of this book will benefit researchers and engineers in the field of power engineering, especially in the field of power circuit breakers and power switching technology.

The volume examines the lives and achievements of women who played determining roles in the history of European academies and in the development of modern science in Europe. These persevering personalities either had a key influence in the establishment of academies ("Patronae Scientiarum") or were pioneering scientists who made major contributions to the progress of science ("path-breakers"). In both cases, their stories provide unique testimonies on the scientific institutions of their time and the systemic barriers female scientists were facing. Conceptualized as a transversal series of biographical portraits, the contributions focus particularly on each personalities’ role in (or relation to) European academies, ensuring both a geographical and disciplinary balance. The co-editors of the volume are Professor Ute Frevert (Co-Director at the Max Planck Institute for Human Development), Professor Ernst Osterkamp (President of the Deutsche Akademie für Sprache und Dichtung) and Professor Günter Stock (former ALLEA President).

We seem to notice only to types of success. Those achieved by people who have attained demi-God status and others from the West, who we blindly try to emulate. How many times do we look at people, close home, who are much like us! People living a life like one we live, with dreams like the ones we have, facing challenges like the ones we do. These people no different from us, are yet, far ahead of us. They have lived a life, which although very similar, is quite different from ours. This book is a collection of real life stories of some extraordinary achievers. They come from all walks of life, from every corner of India, cutting across all age groups. They dared to defy the trend and refused to join the rat race. They have moved away and walked ahead. They have path-breakers. Their life and work should serve as an assurance and source of motivation to those who desire to follow their instinct and take the road less travelled.
