Electromagnetic Wave Applications for Reliable Fault Detection in Power Transformer Windings

This paper presents a novel approach for the localization of radial faults in power transformer windings using electromagnetic waves, emphasizing the critical issues of reliability and noise. The proposed analytical method aims to enhance the reliability of power transformers by effectively identifying and diagnosing radial deformations. The study utilizes matched filtering techniques to analyze received signals, ensuring improved accuracy despite environmental noise interference. By comparing the reference signals from healthy transformers with those from faulty conditions, the methodology demonstrates a robust framework for real-time monitoring. The findings indicate that addressing noise and reliability significantly contributes to the effectiveness of fault detection systems in power transformers.
