    A power transformer is a critical electrical device utilized in both transmission and distribution of electrical power to ensure the reliability, stability, and optimal performance of modern electricity networks. Transformer safety plays a crucial role in the management and operation of electricity networks. The main objective of transformer protection is to identify and isolate internal or external imperfections in order to reduce damage and preserve the integrity of the electrical system. Transformer safety involves challenges such as handling high inrush currents during startup, accurate fault detection and coordination with other network protection devices. To ensure safe and continuous power supply, it is necessary to have in-depth knowledge of electrical principles, protection technologies and maintenance strategies additional to fault detection, analyze and management to increase the efficiency and the reliability of power transformer. The problematic addressed in this thesis focuses on understanding the fault mechanisms, evaluating the effectiveness of existing protection systems, and developing maintenance strategies to mitigate the risk of transformer failures. Through detailed simulations and analysis, the thesis seeks to provide actionable insights into enhancing the reliability and efficiency of power transformers within the operational framework of Electro-Industries.
