A delta connected motor has a resistance of 850 mohm and inductance of 2,5 mH. This motor receives a line voltage of 400 V at a frequency of 50 Hz. This supply is obtained from a 50 kVA delta/star transformer. This transformer has a no load current of 2,55 A at a lagging power factor of 0,121. Fully describe the primary line current of this transformer for the given load, when it is fed by 11 kV transmission lines.
