Book excerpt: This book deals with the Experiments with the basic electrical circuits with AC and DC supply, fundamental theorems with AC and DC supply, DC machines, Single and Three phase transformer, Induction machines, Synchronous machines and Drives. The first chapter of the book deals with the Basics of Experimentation. It explains the general instructions and precautions to be taken while performing the experiments in an electrical engineering laboratory. Some of the topics covered are enlisted as- electric supply systems, details of instruments used in laboratory, electrical symbols and standards of common use. The chapter also brings up the fundamental concepts of report writing with a special emphasis on plotting a graph.The second chapter comes up with the experiments on electrical circuits with DC supply. For simplicity the experiments are explained with DC supply, though these fundamental theorems are equally valid for the AC supply and the DC supply. The third chapter deals with the electrical circuit with AC supply to make the students comfortable in the concepts of impedance, phasor diagram, resonance and power measurements in AC supply based circuits.The fourth chapter includes the experiments on DC Machine for the performance analysis, load testing, speed control etc. In this chapter, various experiments on the DC drive including the breaking, static control of DC series motor and chopper fed DC motor drive in software MATLAB. The fifth chapter covers the experiments on the single and three phase transformer the performance analysis, testing, parallel operation, parameter evaluation etc.The sixth chapter of the book includes the experiments on the induction machines for its performance evaluation, testing, parameter evaluation, speed control etc. This chapter also covers the experiments on induction motor breaking, analysis of inrush current and speed control using soft wares MATLAB and PSIM. This chapter also includes the experiment on the working of an induction machine as a self-excited induction generator. The last chapter of the book covers the experiments on the Synchronous Machines (alternator and motor) for its performance evaluation, parameter measurements etc.As it is the first volume, the main focus of the book is to provide the clear concept with an easy approach. In future, if the Almighty God gives me the opportunity, some fundamental questions and typical questions will be added for more understanding of the experiments and viva-voice examination. The author of the book has a prolonged experience of teaching of more than twenty years at a college of National Importance in India namely National Institute of Technology, Kurukshetra in Electrical Engineering department. I hope this book would turn out to be useful to the students of Electrical Engineering at degree and diploma level.First of all, I want to thank the almighty God and I express my deep sense of obligation to all those, who have directly or in-directly contributed in the successful completion of this book My special thanks to my obedient student Mr. Priyavrat Vats, M.Tech, NIT, Kurukshetra for sparing his valuable time to help me to draw figures and tables and investing in the book in one way or the other. I feel deeply enlightened to express my gratitude to my parents and my family because without their support this task would have been impossible. Since it is my very first attempt at writing a book, I would be grateful to the readers or users of this book for their valuable suggestions for future improvement of this book.
