The High Voltage Technique (Isolation and Overvoltage). At 2 p.m.. H. 1. Electric discharges in gases. External insulation air" authored by A. C. Krasko is a fascinating and deep dive into the world of high-voltage technology that will be of interest to both professional engineers and students studying electrical engineering and related disciplines. In the first part of this large-scale work, the author focuses on electric discharges in gases and external insulation, which is a fundamental aspect for understanding the operation of high-voltage systems. The book begins with the basics, explaining how and why electrical discharges occur in gases. Krasko not only expounds the theory, but also reinforces it with practical examples, which makes the material accessible and understandable. The reader will be able to learn about the different types of discharges, such as crown, spark and arc, as well as the factors that affect their occurrence. This information will be useful not only for specialists working in the field of electricity, but also for those who are interested in the physics and chemistry of processes occurring in the atmosphere. The book also raises important topics regarding insulation in high-voltage systems. The author examines in detail the designs and materials used to provide reliable insulation, as well as the methods of testing and evaluating their effectiveness. This is especially true for engineers involved in the design and operation of electrical networks, since the right choice of insulation materials can significantly reduce the risk of accidents and improve the safety of equipment operation. Krasko has a unique style of presentation that combines scientific rigor and accessibility. His approach to the presentation of material allows the reader not only to assimilate information, but also to develop critical thinking, which is especially important in technical disciplines. The author is also known for his other works in the field of electrical engineering, which have received recognition among specialists. His books are often used in educational institutions and in advanced training courses. This book will be of interest not only to undergraduate and graduate students, but also to practicing engineers working in the field of energy, electronics and related technologies. It will be an excellent addition to the library of any specialist who seeks to deepen their knowledge of high-voltage systems and modern methods of their protection. Readers interested in topics such as electrical discharges, insulation, overvoltage and their impact on the operation of electrical equipment will find a lot of useful information in this book. If you are looking for literature that will help you understand the complex aspects of high voltage technology, then the “High Voltage Technique” is what you need.
