Two single phase transformers are connected in parallel to supply an impedance load of (0.8+j0.6)pu at a voltage of 1<0 opu. The transformers have an impedance of (0 + j0.1)pu each.

Consider one of the transformers is operating with 5% higher tap on the load side. After operation with above tap condition load was disconnected, however terminal voltage is still 1<0opu

Calculate the following:

(a) Calculate the current flows on the secondary (load) side of the transformers

(b) Calculate the current flows on the primary (source) side of the transformers

(c) Calculate the current supplied by the source
