Inrush current or input surge current refers to the
maximum, instantaneous input current drawn by an electrical
device when first turned on.Alternating current electric
motors and transformers may draw several times their normal
full-load current when first energized, for a few cycles of
the input waveform. .
When a transformer is first energized a transient current
much larger than the rated transformer current can flow for
several cycles. This is caused because the transformer will
always have some residual flux density and when the
transformer is reenergized the incoming flux will add to
the already existing flux which will cause the transformer
to move into saturation.this transient current is called as
inrush current.
