On-load tap changers (OLTCs) are crucial components within power transformers, enabling voltage regulation while the transformer remains energized. Maintaining the health of OLTCs is essential for ensuring grid reliability and efficient power delivery. Traditionally, diagnosing potential problems in OLTCs relied on intrusive methods like offline inspections or taking oil samples for analysis. These techniques require taking the transformer out of service, leading to downtime and increased maintenance costs. Vibro-Acoustic (VAM) technology offers a promising alternative,...
Vibro-acoustic diagnostics have emerged as a rapid and non-invasive method to monitor and assess the health of On Load Tap Changers (OLTCs) in electrical power systems. This technology detects and analyzes the vibrations and sound patterns generated by OLTCs during operation, helping to identify...
