About this Item

Electrical machines form an integral part of a large electrical power system, with other components as well. The aim of this book is to give detailed theory of the experiments on the electrical machines. This laboratory manual on electrical machines is meant for electrical engineering students of B.E. and B. Tech. and polytechnics in India and abroad. This book gives the basic information to the students with the machine phenomenon, working principles and testing methods, etc. It also imparts a real physical understanding of various types of electrical machines. The main attraction of this laboratory manual is its power point presentation for all experiments. With the help of this any college or institute can conduct these experiments using available machines with little modifications. By studying this PPT, an average student can also perform the experiments with great interest and enthusiasm. The experiments in this manual are broadly divided as: 1. Experiments for second year of B.E. or B.Tech. 2. Experiments for third year of B.E. or B.Tech. 3. Experiments for second and third year of polytechnics. The conclusion written at the end of each experiment will help the student as well as working engineers, to know the behavior of various machines. This book will be a valuable asset to the practicing engineers, teachers and students. Contents: Experiment 1. To Study the Speed Control of a DC Shunt Motor by (a) varying armature voltage with field current kept constant. (b) varying field current with armature voltage kept constant. Experiment 2. To Perform Load Test on a DC Shunt Generator. Experiment 3. To Perform Open Circuit and Short Circuit Test on a Single-Phase Transformer Experiment 4. To Study (a) the Polarity Markings on Single-Phase Transformer Windings and (b) the Operation of an Autotransformer. Experiment 5. To Study the Load Test on a Cumulatively Compounded DC Motor. Experiment 6. To Study the Load Test on a Three-Phase Induction Motor. Experiment 7. To Determine Voltage Regulation and Efficiency of a Single-Phase Transformer by Direct Loading. Experiment 8. To Study the Scott-Connection of Transformers (Three-Phase to Two-Phase Conversion). Experiment 9. To Study the Variation of Speed and Load Test on Schrage Motor. Experiment 10. To Plot V and Inverted V(?) Curves of a Synchronous Motor Experiment 11. To Determine the Ratio Xq/Xd for Three-Phase Alternator by using ?Slip Test? Experiment 12. To Study the Synchronization of an Alternator with an Infinite Bus by ?Dark Lamp Method? Experiment 13. To Determine Potier Reactance of Three-Phase Alternator by ?Zero Power Factor Lagging Saturation Curve? Experiment 14. To Determine Negative Sequence and Zero Sequence Reactances of Synchronous Generator. Experiment 15. To Study the Characteristics of Three-Phase Induction Generator. Experiment 16. To Determine Direct Axis Subtransient (Xd?), Quadrature Axis Subtransient (Xq?) Reactances of Synchronous Machine. Printed Pages: 224. Bookseller Inventory # 84468
