SUMMARY:The Case of the Transformer That Hummed at Midnight
DESCRIPTION:The live presentation of this event has already taken place. \nPlease view the PDF slides here or watch the video recording below: \n \nEmeritus Professor Akhtar Kalam’s Electrifying Mysteries\nThis webinar series provides a structured examination of real-world engineering challenges. Each session will address specific\, technically focused topics relevant to professional engineers. \nWebinar details\nA 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. \n\nThe webinar will be recorded and will be sent out to registered attendees afterwards.\nA certificate of attendance will be provided to attendees who request one near the end of the live webinar session.\nPlease note: the time stated on this event is in UTC. You will need to convert this to your own time zone.\n\nKey takeaways from this webinar\n\nUnderstand the physical and electrical origins of transformer hums and vibrations.\nLearn systematic investigative approaches to diagnose magnetostriction\, core saturation\, and harmonic interactions.\nApply vibration and harmonic monitoring techniques to identify non-linear loading impacts.\nIntegrate acoustic and electrical data for condition-based maintenance and diagnostic decision-making.\n\nRelated courses\nThis webinar/topic relates to our school of Electrical Engineering and is particularly found in the following courses: \n\nProfessional Certificate of Competency in Big Data and Analytics in Electricity Grids\nProfessional Certificate of Competency in Smart Grids\n52892WA Advanced Diploma of Electrical and Instrumentation (E&I) Engineering in Mining\nProfessional Certificate of Competency in Circuit Breakers\, Switchgear and Power Transformers\nOnline – Bachelor of Science (Electrical Engineering)\n\nTo learn more about tuition fees\, please click here. \nAbout the presenter\n \nEmeritus Professor Akhtar Kalam \nBSc\, BScEng\, MS\, PhD\, FIET\, CEng\, FAIE\, FIEAust\, CPEng\, NER\, APEC Engineer\, IntPE(Aus)\, PEV\, MCIGRE\, Life Senior Member of IEEE. \nProfessor Akhtar Kalam is a supervisor of EIT’s Doctoral students. He has worked at Victoria University since 1984 and recently associated with the Institute for Sustainable Industries and Liveable Cities. He is the Editor in Chief of Australian Journal of Electrical & Electronics Engineering. Further\, he has Distinguished Professorship position in many national and international institutions. He has been recognized internationally and nationally for his research. He is regularly invited to deliver lectures\, work on industrial projects\, and examine external theses overseas. Professor Kalam is a registered Professional Engineer in the state of Victoria (PEV)\, Fellow of EA\, IET\, AIE\, a life Senior Member of IEEE\, NER\, APEC Engineer\, IntPE (Aus) and a member of CIGRE AP B5 Study Committee. \n\n \nEmeritus Professor Akhtar Kalam’s Electrifying Mysteries\nThis webinar series provides a structured examination of real-world engineering challenges.
