This book is devoted to one of the main problems of modern electrical power engineering—power transformer diagnostics. The first three chapters discuss the fundamentals: The first chapter presents the physical reasons for power transformers’ failures and the technical and economic consequences of disruption of the normal operation. The second chapter reviews the standard technologies for monitoring the state of the high-voltage transformers. The third chapter tells about monitoring the condition of transformer windings based on the pulse method. The fourth chapter presents the technologies for transformer windings condition controlled by means of nanosecond pulses. The stages of improving the pulsed method based on a short probing pulse of the nanosecond range, the results of experiments on identifying the radial and axial displacements of the winding, studies of the effect of the duration and shape of the probing pulse on the sensitivity of the diagnostic procedure, and the stages of developing a mathematical as well as physical model of a power transformer are consistently presented.

This textbook covers in detail the problem of improving the reliability and service life of high-voltage equipment in electric power systems, mainly through testing, monitoring, and diagnostics, which support the timely repair or replacement of equipment. The main focus is on high-voltage power and instrument transformers, switching devices, powerful rotating electric machines, capacitors, bushings, and power cables.The design, purpose, and principle of operation for each respective type of equipment, as well as adverse factors that can lead to defects (primarily in insulation) – and, as a result, to accelerated aging (wear) and failure – are considered.In turn, the scientific and technological foundations and practical application of testing, monitoring, and diagnostics to determine the technical condition of equipment are described. Considerable attention is paid to new and promising methods for testing under voltage (without interrupting operation) – such as pulsed flaw detection and dielectric spectroscopy. In addition, the authors propose a number of helpful physical concepts and technical solutions.The book stands out in terms of the breadth and depth of the consideration of the problem, which reflects recent trends and concepts for the development of the electric power industry, and its convincing demonstration of the capabilities of traditional and advanced methods in relation to the main equipment used in electric power systems.The textbook is intended for undergraduate and graduate students in the field of high-voltage technologies for electric power systems. It also benefits engineering personnel working with electric power systems and in the electrical industry.

This book aims to provide readers with practical knowledge of the fundamentals of the “digital transition” concept, tools for designing and managing the operation of smart grids and substations, and critical issues in modernizing the energy sector. The inevitable transformation of the electric power industry is moving toward digitalization, which has taken the form of the concept of "Intelligent (smart) grids" (sometimes called "Digital Transition"). This has required coordinated work not only from the energy industry, but also from other stakeholders (government agencies, private firms, utilities, scientific and educational institutions, etc.) to solve numerous problems that arise during the transition to this advanced technology. It is obvious that the development of new components of energy systems, such as smart meters, monitoring and geolocation equipment, new disaster recovery systems, and energy storage systems, should be supplemented by the creation of the necessary communication infrastructure, modernization of existing network components, implementation of relevant regulations, training of highly qualified personnel.The book covers all the main tasks and ways to solve them for the implementation of this technology. It summarizes materials from numerous monographs, scientific articles, and conference reports discussing these issues.

This book is a comprehensive scientific and practical guide to the digital transformation of industrial power systems. This book explores how artificial intelligence, real-time monitoring, and predictive analytics are reshaping the management of electricity in energy-intensive industries with continuous production cycles—such as metallurgy, chemical processing, and cement manufacturing. The core motivation behind this book lies in a global industrial challenge: how to ensure energy efficiency, reliability, and operational stability while maintaining uninterrupted technological processes. Traditional methods of load control and energy optimization are no longer sufficient in an era defined by Industry 4.0, Smart Grid technologies, IoT integration, and cyber-physical systems (CPS). This book bridges classical electrical-engineering theory with the latest advances in AI-driven forecasting, SCADA/EMS/BEMS systems, digital twins, and machine-learning-based optimization, offering readers both theoretical depth and actionable engineering tools. Across six logically connected chapters, this book guides readers from the fundamental laws of power consumption and system reliability to advanced topics such as adaptive-predictive architectures, stochastic modeling of industrial loads, and multi-agent control for real-time decision-making. Mathematical models, algorithmic frameworks, and applied case studies demonstrate how enterprises can reduce losses, manage reactive power, and forecast demand with higher precision. Each section combines analytical rigor with implementation strategies that can be directly applied in industrial environments. This book’s novel contribution lies in its interdisciplinary integration of electrical engineering, system theory, data science, and artificial intelligence into one unified methodological framework. It introduces an integral indicator of energy efficiency tailored for continuous production and proposes a hybrid AI-based control architecture capable of self-learning and adaptation under uncertainty. Written for a broad professional audience, this book benefits energy engineers, researchers, graduate students, and decision-makers involved in power supply, automation, and digital-energy management. Policymakers and sustainability strategists find it valuable for understanding how intelligent control systems can support national goals in green energy transition, industrial modernization, and carbon-reduction strategies. By combining theoretical insight with real-world relevance, this book serves as both a reference manual and a visionary roadmap for designing the next generation of intelligent, stable, and energy-efficient industrial power systems—a critical step toward the sustainable factories of the future.
