1. provides “step by step” procedures of designing a transformer so that engineers without prior knowledge or exposure to design can follow the procedures and calculation methods to acquire reasonable proficiency of designing a transformer. 2. functions as a useful guide for the practicing engineers to undertake new designs, cost optimization, design automation etc., without the need for external help or consultancy. 3. covers in detail the design processes with necessary data and calculations of a wide variety of transformers including Dry Type Cast Resin Transformer, Amorphous Core Transformer, Earthing Transformer, Rectifier Transformer, Auto Transformer, Transformers for Explosive Atmosphere, Solid State Transformer etc. 4. includes subjects like, Carbon Footprint Calculation of Transformers, Condition Monitoring of Transformers and Design Optimization Techniques. 5. based on the 50+ years experience of the author in the Power and Distribution Transformer industry.
Covering the fundamental theory of electric power transformers, this book provides the background required to understand the basic operation of electromagnetic induction as applied to transformers.
Despite the powerful numerical techniques and graphical user interfaces available in present software tools for power system transients, a lack of reliable tests and conversion procedures generally makes determination of parameters the most challenging part of creating a model. Illustrates Parameter Determination for Real-World Applications Geared toward both students and professionals with at least some basic knowledge of electromagnetic transient analysis, Power System Transients: Parameter Determination summarizes current procedures and techniques for the determination of transient parameters for six basic power components: overhead line, insulated cable, transformer, synchronous machine, surge arrester, and circuit breaker. An expansion on papers published in the IEEE Transactions on Power Delivery, this text helps those using transient simulation tools (e.g., EMTP-like tools) to select the optimal determination method for their particular model, and it addresses commonly encountered problems, including: Lack of information Testing setups and measurements that are not recognized in international standards Insufficient studies to validate models, mainly those used in high-frequency transients Current built-in models that do not cover all requirements Illustrated with case studies, this book provides modeling guidelines for the selection of adequate representations for main components. It discusses how to collect the information needed to obtain model parameters and also reviews procedures for deriving them. Appendices summarize updated techniques for identifying linear systems from frequency responses and review capabilities and limitations of simulation tools. Emphasizing standards, this book is a clear and concise presentation of key aspects in creating an adequate and reliable transient model.
This book presents the proceedings of the 5th International Colloquium “Transformer Research and Asset Management,” held in Opatija, Croatia, on October 9–12, 2019. The papers chiefly focus on three groups of topics: 1. Numerical Modeling: Electromagnetic fields—Coupled fields—Transients—Numerical modeling in design 2. Materials, Components and New Technologies: Insulating materials—Magnetic materials and transformer noise—Transformer components—New transformer technologies 3. Transformer Lifecycle Management: Diagnostics and monitoring—Failure—Asset management—In-service experiences. The Colloquium was organized by the Croatian National Committee of CIGRE together with the Faculty of Electrical Engineering and Computing in Zagreb and the Centre of Excellence for Transformers
This recommended practice provides short-circuit current information including calculated short-circuit current duties for the application in industrial plants and commercial buildings, at all power system voltages, of power system equipment that senses, carries, or interrupts short-circuit currents.
A thorough analysis of basic electrical-systems considerations is presented. Guidance is provided in design, construction, and continuity of an overall system to achieve safety of life and preservation of property; reliability; simplicity of operation; voltage regulation in the utilization of equipment within the tolerance limits under all load conditions; care and maintenance; and flexibility to permit development and expansion.
