Electromagnetic–Mechanical–Acoustic Coupling Analysis of Transformers Under Geomagnetically Induced Current Interference

Electromagnetic–Mechanical–Acoustic Coupling Analysis of Transformers Under Geomagnetically Induced Current Interference

During geomagnetic storms, a geomagnetically induced current (GIC) flows into grounding transformers, potentially causing anomalous vibrations and audible noise in internal components. This study establishes an electromagnetic–mechanical–acoustic coupling (EMAC) model to characterize the multi-physi...
