Two Identical single-phase 200 kVA, 220/440 V are supplying a 3-phase load at 440 V in open-delta mode. The power factor of the load is 0.7 lagging. Calculate the following:

(a) The maximum secondary side line current without overloading the transformer.

(b) The amount of real power delivered by each transformer.

(d) A third identical transformer is now added to complete the closed delta.

Calculate the percentage increase in real power supplied. Assume that the load voltage and pf remain same as 440 V and 0.7 pf lagging.

Develop Simulink model demonstrating this open - delta mode and verify the results obtained showing the respective waveforms.
