if a damaged 500kva transformer with %impedance 2.6 is
replaced by two transformers of 250Kva with different %
impedance will they be able to catter the load. what will
be the ratio of load on the two transformers if the %
impedance is in the ratio 1:2
Answer Posted / k.prakashchandra
The above is correct.But transformers with same capacity and
voltage having % impedances in the ratio 1:2, is not
believable.The load sharing will be in 2:1 ratio if they are
connected in parallel.
