IOT Based Real Time Substation Power Line Auditing System For MSEDCL

As the complexity of electrical distribution networks increases, the need for automation in substations becomes essential for ensuring the reliability and quality of power delivery. This paper presents a system designed to monitor and protect electrical circuits in real time by acquiring key parameters such as voltage, current, frequency, and temperature from power stations. These values are continuously transmitted over a network for monitoring and displayed on a screen. The system compares the real-time data with predefined limits, triggering a relay and buzzer if any parameter exceeds the threshold. If the fault persists, the relay isolates the affected load from the system, ensuring safety. This system, based on an Arduino Uno microcontroller, provides automated fault detection, protection, and timely alerts. The proposed design demonstrates how automation and monitoring can enhance power system reliability and prevent potential damage to infrastructure.
