AOUABDI, Mohamed Diaa EddineTAAMOURT, Mohammed El AmineBerrached, Djelloul2025-07-212025-07-212025http://dspace.univ-temouchent.edu.dz/handle/123456789/6726This bibliographic study focuses on electrical disturbances in low-voltage networks, such as amplitude variations (voltage dips, surges), distortions of the sinusoidal wave (harmonics, carrier currents), imbalances in polyphase systems, and electromagnetic disturbances, which pose major challenges. Their study revolves around identifying their origins, their impact on equipment, and appropriate technical solutions. Through theoretical analyses, this work proposes a rigorous methodology to diagnose, prevent, and correct these disturbances, ensuring better energy quality and compliance with standards.frThesis
