Calculate pf and load shared by each transformer.

A load of 1400 KVA at 0.866 pf lagging is supplied by two three phase transformer of 1000 KVA and 500 KVA operating in parallel. The ratio of transformation is same in 6600/400 delta/star. If the equivalent secondary impedance are $(0.001+j0.003)\Omega$ and $(0.0028+j0.005) \Omega$ per phase respectively.

Calculate pf and load shared by each transformer.
