Item Etat de L’art de Génie Electrique(University of Eloued جامعة الوادي, 2024) Laouamer,mosbahThe document provides a detailed academic discourse on electrical engineering, integrating foundational and advanced topics crucial for both theoretical understanding and practical application. It begins by elucidating the fundamental principles of electricity, rooted in atomic structure, and explores the classification of materials into conductors, insulators, and semiconductors, emphasizing their roles in electrical conductivity. The document systematically investigates power generation methods, covering hydroelectric, thermal, wind, solar, and nuclear energy, alongside their operational principles, environmental impacts, and efficiency parameters. Key components of the electrical grid, including high-voltage lines, transformers, and distribution networks, are analyzed to demonstrate the complexities of energy transportation and delivery. In addition to power systems, the text highlights the importance of safety measures, such as grounding techniques and the implementation of protective devices like differential circuit breakers, to mitigate risks associated with electrical hazards like electrocution and electrification. It also delves into signal processing, discussing the nature and manipulation of analog and digital signals, as well as the mathematical frameworks underlying signal analysis, filtering, and modulation. Furthermore, the role of electronic components such as diodes, transistors, and operational amplifiers is explored, with a focus on their applications in rectification, amplification, and circuit design. This comprehensive document not only bridges the gap between theoretical concepts and industrial practices but also emphasizes the interdisciplinary nature of electrical engineering, linking it with physics, mechanics, and materials science. It serves as an essential resource for students, educators, and professionals aiming to deepen their understanding of electrical systems, their functionalities, and their impact on technological and societal advancementsItem Electric Machines(University of Eloued جامعة الوادي, 2024) ZINE, BachirElectrical machines are a cornerstone of modern electrical engineering, enabling energy conversion and powering countless applications. This course provides a comprehensive understanding of electrical machines, organized into five core chapters.
