The book “Calculations of technological consumption (loss) of electricity for its transport in the electric grids of power systems” by Mikhail Fursan is a unique publication that immerses the reader in the complex but extremely important world of energy. In today's society, where energy resources are becoming increasingly valuable, understanding the processes associated with the transportation of electricity becomes especially relevant. This book is not just a textbook, but a real reference book for professionals, students and anyone interested in energy and sustainable development. The author focuses on calculations of technological losses of electricity arising in the process of its transportation through electric grids. Fursanov delicately and thoroughly examines both the physical and economic aspects of this problem. It explains how various factors, such as resistance of conductors, line lengths and equipment operating modes, affect the transmission efficiency of electricity. The reader will be able to learn about methods to minimize losses, which is especially important for energy companies seeking to optimize their costs and improve the reliability of supplies. The book will be of interest not only to professional power engineers, but also to students of technical universities studying in specialties in the field of electrical engineering and energy .. It will be an excellent addition to the training materials, allowing a deeper understanding of the theoretical foundations and practical aspects of electricity loss calculations. Also, this publication can attract the attention of managers and managers working in the field of energy companies who seek to improve the efficiency of their business processes. The topics raised in the book cover a wide range of issues, including the impact of new technologies on loss reduction, the use of alternative energy sources, and the introduction of smart grids. Fursanov focuses on the importance of sustainable development and the need to transition to more efficient energy management. This book could form the basis for discussion of broader issues related to environmental safety and economic feasibility in the energy sector. Mikhail Ilyich Fursan's style is distinguished by clarity and accessibility. He masterfully combines theoretical calculations with practical examples, which makes the material understandable even for those who are just beginning to get acquainted with this topic. The author is not afraid to delve into technical details, but does it in such a way that the reader does not lose interest and can easily follow his thought. This quality makes the book a valuable resource for both professionals and amateurs. If you are looking for literature that will help you understand complex energy issues, “Calculations of technological consumption (loss) of electricity for its transport in power grids” will be an excellent choice. The book will not only expand your knowledge, but also help you look at energy from a new perspective, realizing the importance of each element in the power transmission chain. Do not miss the opportunity to immerse yourself in a world where every calculation matters, and every loss can be minimized.
