Switchgear Protection and power systems written by famous writer Sunil S Rao Most of Electrical students and faculty members are searching for this in Internet here i am providing this book only for reference purpose. About The Book A Switchgear or Electrical Switchgear is a general tern which includes all the switching devices associated with mainly Power system Protection. It also includes all devices associated with control,metering and regulating of Electrical Power System.Assembly of such devices in a logical manner forms a Switchgear. This is very baic definition of switchgear. Switchgear protection plays a vital role in modern power system network, right from generation through transmission to distribution end. The current interruption device or switching device is called circuit breaker in switchgear protection system. The circuit breaker can be operated manually as when required and it is also operated during over current and short circuit or any other faults in the system by sensing the abnormality of system.

The circuit breaker senses the faulty condition of system through protection relay and this relay is again actuated by faulty signal normally comes from current transformer or voltage transformer.
