Switchgear and Protection by Badri Ram Ebook 15
Switchgear and protection are two important aspects of power system engineering. Switchgear refers to the devices that are used to switch, control, and protect electrical circuits and equipment. Protection refers to the methods and schemes that are used to detect and isolate faults in power systems and minimize their adverse effects.
One of the books that covers these topics in detail is Power System Protection and Switchgear by Badri Ram and D. N. Vishwakarma. This book was first published in 2001 by McGraw-Hill Education and later revised in 2011 by Tata McGraw-Hill Education. The book has 684 pages and consists of 15 chapters, each covering a different aspect of switchgear and protection.
