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.
