Utilization of Electrical Energy by Rajput.pdf
Utilization of electrical energy is the study of how to efficiently and effectively use electrical power for various applications. It covers topics such as illumination, electrical drives, electric traction, electrolytic processes, refrigeration and air-conditioning, welding, heating and electric furnaces. One of the books that provides a comprehensive and detailed treatment of this subject is Utilisation of Electrical Power by Er. R. K. Rajput. This book is intended for the students of B.E./B.Tech., A.M.I.E., Diploma and other engineering examinations. It is also useful for practicing engineers and professionals who want to update their knowledge in this field.
The book is divided into 12 chapters, each covering a specific aspect of electrical energy utilization. The chapters are as follows:
- Chapter 1: Illumination: This chapter deals with the principles and methods of lighting, types of lamps, lighting calculations, lighting schemes, standards and codes of illumination.
- Chapter 2: Electric Heating: This chapter explains the various methods of electric heating, such as resistance heating, induction heating, dielectric heating and arc heating. It also discusses the applications and advantages of electric heating.
- Chapter 3: Electric Welding: This chapter describes the different types of electric welding, such as arc welding, resistance welding, gas welding and thermit welding. It also covers the welding equipment, electrodes, power sources and welding techniques.
- Chapter 4: Electrolytic Processes: This chapter covers the basic concepts and applications of electrolysis, such as electroplating, electrorefining, electrotyping, electrometallurgy and electrochemical machining.
- Chapter 5: Refrigeration and Air-Conditioning: This chapter explains the principles and working of refrigeration and air-conditioning systems, such as vapour compression cycle, vapour absorption cycle, refrigerants, psychrometry, cooling load estimation and air distribution systems.
