The Case of the Transformer That Hummed at Midnight

Webinar details

A transformer that hums only at midnight presents both a mystery and a learning opportunity. This webinar explores how seemingly minor design tolerances, magnetic flux anomalies, load harmonics, and resonance phenomena can manifest as audible or electrical disturbances. Participants will be guided through investigative methodologies that combine acoustic analysis, power quality assessment, and magnetic field modelling to uncover the root causes. The session offers practical insights into diagnosing transformer behaviour and ensuring long-term reliability.

• The webinar will be recorded and will be sent out to registered attendees afterwards.
• A certificate of attendance will be provided to attendees who request one near the end of the live webinar session.
• Please note: the time stated on this event is in UTC. You will need to convert this to your own time zone.

Key takeaways from this webinar:

• Understand the physical and electrical origins of transformer hums and vibrations.
• Learn systematic investigative approaches to diagnose magnetostriction, core saturation, and harmonic interactions.
• Apply vibration and harmonic monitoring techniques to identify non-linear loading impacts.
• Integrate acoustic and electrical data for condition-based maintenance and diagnostic decision-making.
