A step-down delta-star transformer, with per-phase turns ratio of 5 is fed from a 3-phase 1100 V source.
The secondary of this transformer is connected through a 3-pulse type rectifier, which is feeding an R load.
The power delivered to the load is 6839.3 Watts.
The maximum value of the load current is √2 x 22 A.
