What is Transformer Inrush Current?Transformer Inrush Current DefinitionTransformer inrush current is defined as the high transient current drawn by a transformer when it is energized.Initial Flux and VoltageAt startup, there is no initial flux, and the flux wave starts from zero, following the voltage waveform.Peak Flux and Core SaturationThe flux can peak at double the steady-state maximum value, leading to core saturation and high inrush current.Transient Nature of Inrush CurrentInrush curren
