DOWNLOAD EBOOKThe work presented in this PhD-thesis concentrates on radial buckling phenomena of power transformer windings made from Continuously Transposed Conductors (CTC). Analytical and simulation-based approaches describe the critical buckling load involving elastoplastic material behavior. A test stand allows verifying the theoretical results based on dynamic short-circuit tests with realistic winding arrangements in air. Acceleration sensors and a high-speed camera are used to measure the winding vibration and deformation. Furthermore, bonded CTCs are characterized by bending tests and a simulation model including the shear strength of the bonding is developed. Another focus is on the impact of the paper insulation wrapped around CTCs and its contribution to the overall mechanical stiffness. On this subject a considerable impact has been discovered. Accelerated aging tests address the mechanical effect of paper aging based on bending tests as well as zero- and wide-span tensile tests and the degree of polymerization (DP).

DOWNLOAD EBOOKRecent catastrophic blackouts have exposed major vulnerabilities in the existing generation, transmission, and distribution systems of transformers widely used for energy transfer, measurement, protection, and signal coupling. As a result, the reliability of the entire power system is now uncertain, and many blame severe underinvestment, aging technology, and a conservative approach to innovation. Composed of contributions from noted industry experts around the world, Transformers: Analysis, Design, and Measurement offers invaluable information to help designers and users overcome these and other challenges associated with the design, construction, application, and analysis of transformers. This book is divided into three sections to address contemporary economic, design, diagnostic, and maintenance aspects associated with power, instrument, and high-frequency transformers. Topics covered include: Design considerations Capability to withstand short circuits Insulation problems Stray losses, screening, and local excessive heating hazard Shell type and superconducting transformers Links between design and maintenance Component-related diagnostics and reliability Economics of life-cycle cost, design review, and risk-management methods Parameter measurement and prediction This book is an essential tool for understanding and implementing solutions that will ensure improvements in the development, maintenance, and life-cycle management of optimized transformers. This will lead to enhanced safety and reliability and lower costs for the electrical supply. Illustrating the need for close cooperation between users and manufacturers of transformers, this book outlines ways to achieve man
