The protection of electrical networks and switchgear is a topic related to our daily life, in a very important method. Reliable protection of the electrical system against incidents such as short circuits is in fact foundation of the reliability of the power system. In turn, this is one of the main reasons why electricity has accepted as an economical and efficient way to transmit energy (or electricity) over long distances. Electrical network protection technology has come a long way since the electromechanical and solid state eras status relay. In fact, today's relays are computers that can detect errors from voltage and current signals recorded by current transformers (CT) and voltage transformers (VT), using signal processing digital Skill. Therefore, the requirements for this subject have changed significantly over time and In fact, this book fills that need in a comprehensive way. This book by GS. Bhuvanesh Oza, Nirmal Kumar C Nair, Rashingh Mehta and Vijay H Makwana provides a good combination of classical and modern treatments for the protection that is so important to starter. The book begins with an introduction to the philosophy of protection, followed by an explanation to electrical, static and digital relays. In particular, the handling of digital relays includes basic Discrete Fourier Transform (DFT) phasor estimation methods and its specializations for protection such as half-cycle and full-cycle algorithms. Then the authors thoroughly evaluated the devices protection (generators, motors, transformers and busbars) as well as power transmission line protection. No electrical system protection treatment would be complete without an introduction to this complex switch called circuit breaker has to handle hundreds of MVA while breaking current due to inductance the nature of the circuit. The authors dedicate three chapters to this aspect. The task of learning is never complete unless one can test one's ability to solve difficult problems. problem or explain some important concept. Book with multiple choice question bank, review Questions and numbers can help students test their understanding of the topic. In summary, in my opinion, this book will be an important resource for both beginners and practitioners alike in the field of power network protection.
