        abstract = {Transformers are critical components in modern power systems, ensuring efficient voltage regulation and reliable power distribution. However, failures caused by overloading, overheating, insulation degradation, and short circuits can result in significant economic losses and service disruptions. Conventional monitoring approaches are largely manual and lack real-time fault detection, making them inadequate for modern power system requirements. This paper proposes a cost-effective and intelligent transformer monitoring and protection system based on GSM technology. The system utilizes an Arduino UNO microcontroller integrated with an ACS712 current sensor and a DHT11 temperature sensor to continuously monitor key operating parameters. When abnormal conditions such as overcurrent or overtemperature are detected, the system initiates immediate protective actions, including relay-based load disconnection, activation of a cooling fan, and buzzer alerts. Additionally, a GSM SIM800L module is employed to transmit real-time SMS notifications to the operator.
The proposed system offers a reliable, low-cost, and easy-to-implement solution, particularly suitable for rural and small-scale industrial applications. It enhances transformer safety, extends operational lifespan, reduces maintenance efforts, and ensures uninterrupted power supply through real-time monitoring and automated protection mechanisms.},
