Transformer Condition Control

Advanced and Traditional Technologies

By: Vasily Ya. Ushakov,Alexey V. Mytnikov,Valeriy A. Lavrinovich,Alexey V. Lavrinovich

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.

High-Voltage Equipment of Power Systems

Design, Principles of Operation, Testing, Monitoring and Diagnostics

By: Vasily Ya. Ushakov,Alexey V. Mytnikov,Ikromjon U. Rakhmonov

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.

Insulation of High-Voltage Equipment

By: Vasily Y. Ushakov,Vasili鎖隝霢kovlevich·Ushakov

High-voltage electrophysical systems used for research in physics are becoming more and more common in engineering applications, as electrical insulation comprises one of the most important constituent components. This is the first monograph dealing comprehensively and on a scientific level with the insulation of such systems. In the first part of the book, the operating conditions and necessary requirements are analyzed, while the main insulation types are outlined. The second part describes the short- and long-term strengths of vacuums and gases, as well as liquid, solid, and hybrid dielectrics as functions of various influencing factors. The third and last part is devoted to the design of high-voltage insulation systems. The knowledge provided by this book will be useful to physicists designing experimental high-voltage devices as well as to electrical engineers in high-voltage technology, electrical insulation, and cable industries.

Impulse Breakdown of Liquids

By: Vasily Y. Ushakov,V. F. Klimkin,S. M. Korobeynikov

The book describes the main physical processes and phenomena in pulsed electric breakdown. The knowledge and the control of the electric breakdown of liquids is important not only for the insulation inside power systems but it is also used for the creation and information of high voltage and high current pulses. Such high-voltage micro- and nanosecond pulses find wide application in experimental physics, electro discharge technology, physics of dielectrics, radar detection and ranging, high-speed photography.
