Switchgear protection refers to the use of protective devices to safeguard electrical power systems against abnormal operating conditions such as short circuits, overloads, and faults. The primary objective of switchgear protection is to minimize damage to equipment and prevent power outages, thereby ensuring the reliability and continuity of electrical power supply. Sunil S. Rao's book emphasizes the importance of switchgear protection in power systems, highlighting the types of faults that can occur, such as symmetrical and asymmetrical faults, and the effects of these faults on power systems.
The primary strength of Sunil S. Rao’s book lies in its comprehensive scope. The title itself bifurcates the subject matter into two interdependent pillars: switchgear (the apparatus) and protection (the philosophy and logic). switchgear protection and power systems by sunil s rao pdf
