About The Book. Switchgear Protection and Power Systems details the principles and practices of modern power system engineering. The book contains complex phenomena coupled with switchgear, protection, fault calculation, power system analysis-operation-control-automation, digital relays, microprocessor-based relays and microprocessor-based integrated control and protection systems, energy systems, electrical safety, and applications of switchgear. The book also briefs old conventional protection and switching devices in conjunction with new type of devices and techniques. The new chapters like switchgear applications, electrical safety, recent advances in intelligent circuit breakers, applications of fiber-optics cable, compact intelligent substations, ISO, and TQMI are useful additions. It also illustrates the correlation between the energy sector and the power sector.
