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 potential issues before they lead to failure. However, accurate vibro-acoustic monitoring faces challenges, notably distinguishing between normal operational noise and signals indicative of a fault, especially in the presence of ambient...
