        abstract = {Transformers play a vital role in the generation, transmission, and distribution of electrical power by stepping up or stepping down voltage levels efficiently. Given their continuous operation and exposure to high electrical and thermal stress, transformers are prone to various faults such as overload, short circuit, insulation failure, oil leakage, and temperature rise. These faults, if not detected and addressed promptly, can lead to severe damage, costly downtime, and safety hazards including fire and explosion.
This paper presents a comprehensive study of the safety devices employed in transformers to prevent such incidents and ensure reliable operation. The key devices covered include the Buchholz relay for detecting gas accumulation due to internal faults, oil temperature indicators and winding temperature sensors for thermal protection, pressure relief valves to release excessive internal pressure, surge arresters to safeguard against voltage spikes, and fuses or circuit breakers for overcurrent protection. Additionally, the importance of regular maintenance and testing of these devices is discussed. Furthermore, the paper explores recent technological advancements, such as the integration of Internet of Things (IoT) and smart monitoring systems, which allow real-time data collection and remote diagnostics to predict faults before they escalate. Case studies of transformer failures due to lack of protective devices are also analysed to emphasize the necessity of a robust safety mechanism. The findings of this study aim to contribute to the improved design, selection, and implementation of safety devices, thereby enhancing the operational safety, reliability, and efficiency of power transformers in modern electrical networks.},
