Fundamentals of Power System Transformers: Modeling, Analysis, and Operation

“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.
