The book "Unsymmetric Short Circuits in Electrical Systems", written by the team of authors, is an important and relevant work for anyone interested in electrical engineering and energy systems. This publication will be an indispensable assistant for both undergraduate and graduate students, as well as for practicing engineers working in the field of design and operation of electrical networks. This book discusses in detail aspects related to asymmetrical short circuits - a phenomenon that can lead to serious consequences in the operation of electrical systems. The authors explain what a short circuit is, how it occurs, and what mechanisms underlie its occurrence. They emphasize that asymmetric short circuits can significantly affect the stability and reliability of electrical systems, which makes the study of this topic especially relevant. The book covers a wide range of topics, including methods of analysis and calculation of non-symmetric short circuits, as well as their impact on various elements of electrical systems. The authors share their knowledge about modern approaches to the diagnosis and elimination of the consequences of short circuits, which makes the material not only theoretically sound, but also practically applicable. Readers will be able to learn about the latest advances in the protection of electrical systems and how to choose the right equipment to minimize the risks associated with short circuits. This book will be of interest not only to specialists in the field of electrical engineering, but also to those who are engaged in the design and operation of energy systems. Students of technical universities, graduate students, as well as practicing engineers will find in it a lot of useful information that will help them to deepen their knowledge and skills. In addition, the book will be useful to teachers who will be able to use it as a teaching aid for their students. The style of the authors is distinguished by the clarity and accessibility of the presentation, which makes it easy to assimilate complex technical concepts. Each section of the book is accompanied by examples and illustrations, which makes the material more visual and understandable. The authors strive to convey to the reader not only theoretical aspects, but also practical recommendations, which makes the book especially valuable for those who work in this field. The book "Unsymmetric Short Circuits in Electrical Systems" can be compared with other well-known works in the field of electrical engineering, such as "Electric Machines" and "Basics of Electrical Engineering" .. These books also raise important questions regarding the design and operation of electrical systems, but this edition focuses on a specific topic, making it unique. If you are looking for a deep and comprehensive understanding of the problem of asymmetrical short circuits, this book will be a real find for you. It will not only expand your knowledge, but also help you become a more competent specialist in the field of electrical engineering. Read, study and apply the knowledge gained in practice and you can significantly increase the level of reliability and safety of the electrical systems with which you work.
