Book excerpt: Excerpt from The Determination of the Constants of Instrument Transformers The determination of the ratio and phase angle of instrument transformers is an important problem, and one in which consider able precision is required for technical work. The principle of the method here described is the same for both current and potential transformers, being an application of the potentiometer method.

Book excerpt: Excerpt from Determination of the Ratio of Transformation and of the Phase Relations in Transformers Usually the phase of the secondary is so nearly the reverse of the primary phase that the error with high power-factors would be insignificant, but with low power-factors a large error might be introduced, as may be seen by reference to the numerical examples given below. In view of these facts, it is thought desirable to publish the methods of measurement of these quantities in use at the Bureau of Standards. In the vector diagram, Fig. i, are shown the various quantities which go to determine the ratio of the transformer. The length of the vector is proportional to the maximum value of the quantity, and it is considered to be rotating uniformly in a counter clockwise direction. Its projection on a fixed diameter will then represent the instantaneous value of the quantity, assuming it to be sinusoidal. The angles between the vectors represent the phase-angles of the corresponding quantities. represents the magnetic flux linking both primary and secondary windings. It induces in the secondary winding an electromotive force E2 and in the primary winding an electromotive force in the same direction, but of different magnitude, fixed by the number of turns.

Book excerpt: Excerpt from Determination of Current Ratio and Phase Angle of Current Transformers: A Thesis A general outline of the method may be understood from Fig.la. Two non-inductive shunts P and S are connected in the primary and secondary circuits respectively. The drops over these resistances are utilized to send current through the differential coils of the galvanometer G. The construction of this coil will be explained later.

Available in PDF, EPUB and Kindle. Book excerpt: The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory

Book excerpt: The principles of the First Edition--to teach students and engineers the fundamentals of electrical transients and equip them with the skills to recognize and solve transient problems in power networks and components--also guide this Second Edition. While the text continues to stress the physical aspects of the phenomena involved in these problems, it also broadens and updates the computational treatment of transients. Necessarily, two new chapters address the subject of modeling and models for most types of equipment are discussed. The adequacy of the models, their validation and the relationship between model and the physical entity it represents are also examined. There are now chapters devoted entirely to isolation coordination and protection, reflecting the revolution that metal oxide surge arresters have caused in the power industry. Features additional and more complete illustrative material--figures, diagrams and worked examples. An entirely new chapter of case studies demonstrates modeling and computational techniques as they have been applied by engineers to specific problems.

Book excerpt: University Physics is designed for the two- or three-semester calculus-based physics course. The text has been developed to meet the scope and sequence of most university physics courses and provides a foundation for a career in mathematics, science, or engineering. The book provides an important opportunity for students to learn the core concepts of physics and understand how those concepts apply to their lives and to the world around them. Due to the comprehensive nature of the material, we are offering the book in three volumes for flexibility and efficiency. Coverage and Scope Our University Physics textbook adheres to the scope and sequence of most two- and three-semester physics courses nationwide. We have worked to make physics interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. With this objective in mind, the content of this textbook has been developed and arranged to provide a logical progression from fundamental to more advanced concepts, building upon what students have already learned and emphasizing connections between topics and between theory and applications. The goal of each section is to enable students not just to recognize concepts, but to work with them in ways that will be useful in later courses and future careers. The organization and pedagogical features were developed and vetted with feedback from science educators dedicated to the project.
