Electrical Switchgear, Protection & Energy Management : Principles, Designs & Applications

In recent years Electrical Switchgear Protection & Energy Management is being used extensively in Electrical Engineering, Microprocessor, Electrical Drives and Power Electronics research and many other things. This rapid progress in Electrical & Electronics Engineering has created an increasing demand for trained Electrical Engineering personnel. Switchgear essentially consists of switching and protecting devices such as switches, fuses, isolators, circuit breakers, protective relays, control panels, lightning arrestors, current transformers, potential transformers, auto reclosures, and various associated equipment. Switchgear plays a vital role in the overall power distribution and consumption system. Generally speaking, switchboards are the term one uses to designate low voltage switching whereas switchgear connotes HT usage scenarios. The term switchgear refers to a collection of various devices such as:
•Fuses
•Circuit breakers
•Isolators
•Relays, coils
•Disconnect switches
•Current transformers for sensing and monitoring as well as protection

All these components of switchgear may be contained in a suitable metal cabinet that is usually earthed for safety reasons. However, HT distribution systems with large circuit breakers and switchgear are usually housed in a building. Apart from switching on and off electricity supply, switchgear must also control power to the load, detect overload conditions and have features to automatically trip, such as circuit breakers. This protects the equipment that consumes power and it also keeps cables and switchgear protected. Switchgear may also have multiple sources of supply and automatically switch load in case one source fails.

This book is intended for the undergraduate and postgraduate students specializing in Electronics Engineering. It will also serve as reference material for engineers employed in industry. The fundamental concepts and principles behind electronics engineering are explained in a simple, easy- to- understand manner. Each chapter contains a large number of solved example or problem which will help the students in problem solving and designing of switchgear and Protections.
