"Switchgear Protection and Power Systems" by Sunil S Rao is a detailed textbook that covers the fundamental concepts of switchgear protection and power systems. The book provides an in-depth analysis of the principles and practices of switchgear protection, including the design and operation of protective relays, circuit breakers, and other switchgear equipment.
If you are using this book for competitive exams, focus on the following chapters: Master the mathematical derivations.
Sunil S. Rao’s work stands out because it bridges the gap between complex theoretical physics and practical on-site application. If you are serious about a career in Power Systems, having a copy—digital or physical—of this book is an investment in your technical expertise.
What distinguishes Rao’s work from other standard texts, such as those by J.D. Glover or Grainger & Stevenson, is its distinct practical orientation. While Western texts often focus heavily on mathematical modeling and per-unit system analysis, Rao’s approach is deeply rooted in the operational realities of the power utility sector.
