Quality Confirmation Tests for Power Transformer Insulation Systems
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.
Practical Partial Discharge Measurement on Electrical Equipment
Practical Partial Discharge Measurement on Electrical Equipment Accessible reference dealing with (partial discharge) PD measurement in all types of high voltage equipment using modern digital PD detectors Practical Partial Discharge Measurement on Electrical Equipment is a timely update in the field of partial discharges (PD), covering both holistic concepts and specific modern applications in one volume. The first half of the book educates the reader on what PD is and the general principles of how it is measured and interpreted. The second half of the book is similar to a handbook, with a chapter devoted to PD measurements in each type of high voltage (HV) equipment. These chapters contain specific information of the insulation system design, causes of PD in that equipment, off-line and on-line measurement methods, interpretation methods, and relevant standards. The work is authored by four well-known experts in the field of PD measurement who have published hundreds of technical papers on the subject and performed thousands of PD measurements on all the different types of HV equipment covered in the book. The authors have also had relationships with PD detector manufacturers, giving them key insights into test instruments and practical measurements. Sample topics covered in the work include: Physics of PD, discharge phenomena (contact sparking and vibration sparking), and an introduction to PD measurement (electrical, optical, acoustic, and chemical) Electrical PD detection (types of sensors), RF PD detection (antenna, TEV), and PD instrumentation and display Off-line and on-line PD measurements, general principles of PD interpretation, and laboratory PD testing of lumped test objects PD in different types of HV equipment (power cables, power transformers, air insulated metal-clad switchgear, rotating machines, gas-insulated switchgear, and more) For HV equipment OEMs, users of HV equipment, or employees of companies that provide PD testing services to clients, Practical Partial Discharge Measurement on Electrical Equipment is an essential reference to help understand general concepts about the topic and receive expert guidance during specific practical applications.
Fundamentals of Power System Transformers
“Electric machines" and "Transformers" are some of the most challenging electrical engineering courses offered to students. Their complexity arises from numerous prerequisites, a wide array of topics, and a combination of physics and mathematics, presenting students with significant challenges. Fundamentals of Power System Transformers: Modeling, Analytics, and Operation acts as a stepping stone towards a deeper comprehension of the subject matter, resembling the content covered in a graduate-level course. The contents are condensed into two full chapters and four short chapters to provide a self-taught and self-sufficient book for students to solve all problems without the need for a computer. Key features include: A variety of tests to prepare for entrance or employment exams Comprehensive coverage of transformers analysis, control, and protection Numerous problems and solutions with varying degrees of difficulty Problems that can be solved solely using a calculator, without dependence on any computer-based software Two-choice questions to reinforce readers’ understanding of transformers concepts Explores not yet covered subjects including multi-winding auto-transformers, three-phase zigzag transformers, asymmetric and unbalanced three-phase transformers, special transformers, transformer control, and ... This book is aimed at graduate students taking classes in electrical engineering and serves as a valuable reference for researchers and industry professionals interested in emerging technologies and innovations in power system transformers.
