    the transformer function is to transform the same power from side to another side , this can be achieved by the magnetic field inside the iron core , in normal operation no problems but if the transformer is offline and you need to reconnect you have to charge the iron core with the magnetic field so it drawes this high current ( inrush current) to buled up the magnic field at the time of connection
