Chapter 2 summarizes the practices in respect of main switchgear and ancillary equipment for generating stations. Chapter 3 looks into the main parameters of the electrical auxiliary system design and the details of the switchgear, motors, and associated equipment. Chapter 4 describes the construction and assembly, design, operation, and maintenance of transformers. This chapter also covers the development of power cables for transformers, installation, and commissioning tests. Chapter 5 examines the role of protection in system design and the principles and operation of automatic voltage regulators. This book is of great value to workers and students who are interested in the design and operation of electrical plant equipment.
