Fault Detection in Overhead Transmission Lines with SMS Notification

Abstract: THigh-voltage electricity transmission through overhead lines is a critical component of modern power infrastructure. However, maintenance and fault detection in these systems pose significant safety and operational challenges due to the risk of electric shocks and delays in manual intervention. This paper presents an Arduino-based automated fault detection and access control system designed to improve safety, efficiency, and monitoring in power transmission lines. Upon detecting a fault, the system initiates a lockdown by closing barriers on either side of the affected area and simultaneously sends a secure access password to the authorized maintenance personnel via GSM. Access is granted only upon successful password entry using a keypad interface. Additionally, the system features a real-time traffic signaling mechanism, automatic street lighting control, and an overspeed vehicle detection module using IR sensors,which records vehicle data. This integrated solution offers a reliable, cost-effective, and intelligent approach to fault management and public safety in power transmission environments.
