商品簡介
The book covers all the aspects of Electrical Technology for undergraduate course. Various concepts of electrical engineering like power and energy measurement, tariff and power factor improvement, illumination, single phase and three phase transformers, single phase and three phase induction motors, alternators, d.c. machines, special purpose motors and solid state speed control of d.c. and a.c. drives are explained in the book with the help of comprehensive approach. The book starts with review of basic concepts of electrical engineering. Then it explains electrical power measurement methods and electrical energy measurement methods. The book also explains types of tariffs and power factor improvement methods. It includes all the details of illumination schemes. The book further explains single phase and three phase transformers. Then book provides the detailed discussion of three phase and single phase induction motors, d.c. generators and motors and synchronous generators. The discussion of special purpose motors such as servomotors, stepper motors and universal motor is also provided in support. Finally, the book incorporates the discussion of various power devices such as power diodes, SCR, DIAC, Triac, IGBT, Power MOSFETs and then continues to discuss the solid state speed control methods for d.c. and a.c. electrical drives. The book uses plain, simple and lucid language to explain each topic. The book provides the logical method of explaining the various complicated topics and stepwise methods to make the understanding easy. The variety of solved examples is the feature of this book. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
