Every electrical circuit along with high voltage electrical power system requires switching and protective devices. But in high voltage and extra high voltage system, such switching and protective scheme becomes difficult for high fault current interruption in safe and secure way. In addition to that from commercial scenario every electrical power system needs measuring, controlling and regulating arrangement, which is collectively known as switchgear & protection of power system.
1. Fundamental principle of Switchgear & Protection
2. Various types of Circuit interrupting devices
3. Protection concept of Alternator, Transformer, Motor, Busbar & Transmission line.
4. Concept of Neutral Earthing and How to protect from Over voltage.
