Automatic Fault Detection in Three-phase Transmission Lines

Abstract

This report presents the prototype design and implementation of ‘Automatic Fault Detection in Three-phase Transmission Lines’ using Arduino as microcontroller. The goal of the proposed Transmission Line Fault Detection System is to deliver an automated fault detection solution that can quickly and accurately identify and locate faults on transmission lines. The primary objective of this is to establish a rapid and precise identification and localization of faults within transmission lines, ultimately ensuring a seamless and uninterrupted flow of electricity. A prototype of this scheme is developing and testing on a simulated transmission line setting to confirm the system’s performance. The project provides an automatic tripping mechanism for the three-phase supply system to prevent defective damage. Various fault scenarios were artificially introduced to evaluate the system's ability to accurately detect and locate faults. This process allows for a comprehensive assessment of the system’s efficiency and reliability. Focus of this project was to enhance the reliability of three-phase transmission lines by employing voltage imbalance and phase imbalance factors for fault detection. Detailed analysis and calibration of these factors enable the system to swiftly identify faults and initiate timely corrective actions ensuring the uninterrupted flow of electricity within power networks. This proactive approach minimizes disruptions and potential damage, contributing to improved grid stability and efficiency.
