Design and Implementation of a Three Phase Transmission Line Fault Detection and Protection using Arduino

This project addresses the need for Power grids to suffer frequent faults, highlighting the need for improved transmission line protection. This paper proposes an Arduino-based fault detection system for enhanced reliability and safety. The system utilizes current transformers to sense variations and potential impedance measurements for fault location. It also integrates and sound sensors for comprehensive fault detection. Upon fault detection, the Arduino triggers alarms, displays the status on an LCD screen, and can send SMS alerts. This system offers rapid fault identification and response, reducing downtime and Furthermore, Arduino’s low cost makes this a feasible solution for improving power transmission line reliability and safety.
