For any, engineer it is necessary to know the fundamentals of measurements and various modern, measuring instruments. In this context it gives us great pleasure to release this book which, covers the entire revised syllabus of the subject Electrical Measurements., The chapters in the book are arranged in a proper sequence that permits each topic to, build upon earlier studies., The book uses o plain, lucid and everyday language tó explain the subject. The book, prepares very carefully a background of each topic with essential illustrations and practical, exomples. Each chapter is supported with sufficient number of solved problems. The exact and, clear representation of complex diagrams of various instruments and the phasor diagrams, is the, feature of this book. The book covers everything that the students need to familiarize themselves, with the measurement techniques and various instruments. The chapters in the book are, arranged in a proper sequence that permits each topic to build upon earlier studies, which is, important in understanding the subject., The chapter 1 explains the various types of analog measuring instruments., The chapter 2 explains everything about the instrument transformers, their use in power, measurement, power factor meters, frequency meters and synchroscopes., The detail analysis of single phase and three phase power measurement, wattmeters, errors, and compensations and extension of range of wattmeters is included in the chapter 3., The chapter 4 is dedicated to the energy measurement using induction type single and, three phose energy meters., The chapter 5 includes the discussion of various types of d.c. and a.c. potentiometers., The chapter 6 starts with clossification of resistance and then explains the methods of, resistance measurement including d.c. bridges like Wheatstone's bridge, Kelvin's bridge etc., The chapter 7 explains variety of a.c. bridges used for the measurement of parameters R,, L and C., The chapter 8 is dedicated to various mognetic measurements., The book will not only prove useful to the students but also to the subject teachers. The, students have to omit nothing, have to cover nothing more., Copyrighted material, Downloaded From : www.EasyEngineering.net
