Recent catastrophic blackouts have exposed major vulnerabilities in the existing generation, transmission, and distribution systems of transformers widely used for energy transfer, measurement, protection, and signal coupling. As a result, the reliability of the entire power system is now uncertain, and many blame severe underinvestment, aging technology, and a conservative approach to innovation. Composed of contributions from noted industry experts around the world, Transformers: Analysis, Design, and Measurement offers invaluable information to help designers and users overcome these and other challenges associated with the design, construction, application, and analysis of transformers. This book is divided into three sections to address contemporary economic, design, diagnostic, and maintenance aspects associated with power, instrument, and high-frequency transformers. Topics covered include: Design considerations Capability to withstand short circuits Insulation problems Stray losses, screening, and local excessive heating hazard Shell type and superconducting transformers Links between design and maintenance Component-related diagnostics and reliability Economics of life-cycle cost, design review, and risk-management methods Parameter measurement and prediction This book is an essential tool for understanding and implementing solutions that will ensure improvements in the development, maintenance, and life-cycle management of optimized transformers. This will lead to enhanced safety and reliability and lower costs for the electrical supply. Illustrating the need for close cooperation between users and manufacturers of transformers, this book outlines ways to achieve man

This book focuses on oil-paper insulation included in power transformers, especially for EHV and UHV transformers. The importance on insulation ever increased due to a growing voltage rating of transformers. Within the last decades, although research on the transformer insulation and diagnosis methods has advanced a lot, the insulation of HV transformers remained more or less unchanged. The book is divided into five chapters; the first and second chapters explain the basics of oil insulation, while the third chapter focuses on paper insulation. The final two chapters deal with the methods and outcome of testing both techniques. The primary target audience for this book is graduate students and power system engineers.

A comprehensive reference and guide on the usage of the alternative dielectric fluids for transformer insulation systems Liquid-filled transformers are one of the most important and expensive components involved in the transmission and distribution of power to industrial and domestic loads. Although petroleum-based insulating oils have been used in transformers for decades, recent environmental concerns, health and safety considerations, and various technical factors have increased the need for new alternative and biodegradable liquids. Alternative Liquid Dielectrics for High Voltage Transformer Insulation Systems is an up-to-date reference and guide on natural and synthetic ester-based biodegradable insulating liquids. Covering the operational behavior, performance analysis, and maintenance of transformers filled with biodegradable insulating liquids, this comprehensive resource helps researchers and utility engineers expand their knowledge of the benefits, challenges, and application of ester-filled transformers. In-depth chapters written by experienced researchers addresses critical topics including transformer condition monitoring, high voltage insulation testing, biodegradable insulating material processing and evaluation, and more. A unique and significant contribution to existing literature on the subject, this authoritative volume: • Covers condition monitoring, diagnostic testing, applications, maintenance, and in-service experiences • Explores current challenges and future prospects of ester-filled transformers • Discusses significant research progress and identifies the topics in need of further emphasis • Compares the differences and similarities between mineral oils and ester liquids • Includes in-depth behavioral observations and performance analysis of ester-based insulating liquids Alternative Liquid Dielectrics for High Voltage Transformer Insulation Systems: Performance Analysis and Applications is a must-have reference for utility engineers, electrical power utilities, transformer owners, manufacturers, and researchers.

Recent Trends in the Condition Monitoring of Transformers reflects the current interest in replacing traditional techniques used in power transformer condition monitoring with non-invasive measures such as polarization/depolarization current measurement, recovery voltage measurement, frequency domain spectroscopy and frequency response analysis. The book stresses the importance of scrutinizing the condition of transformer insulation which may fail under present day conditions of intensive use with the resulting degradation of dielectric properties causing functional failure of the transformer. The text shows the reader how to overcome the key challenges facing today’s maintenance policies, namely: The selection of appropriate techniques for dealing with each type of failure process accounting for the needs of plant owners, plant users and wider society; and Cost-efficiency and durability of effect. Many of the failure-management methods presented rely on the fact that most failures give warning when they are imminent. These potential failures give rise to identifiable physical conditions and the novel approaches described detect them so that action can be taken to avoid degeneration into full-blown functional failure. This “on-condition” maintenance means that equipment can be left in service as long as a specified set of performance standards continue to be met, avoiding the costly downtime imposed by routine and perhaps unnecessary maintenance but without risking equally expensive failure. Recent Trends in the Condition Monitoring of Transformers will be of considerable interest to both academic researchers in power systems and to engineers working in the power generation and distribution industry showing how new and more efficient methods of fault diagnosis and condition management can increase transformer efficiency and cut costs.
