Figure below shows single-line diagram of a power system. The ratings of the generators and transformers are given below: G1:25 MVA, 6.6kV,xg1=0.20puG2:15 MVA, 6.6kV,xg2=0.15puG3:30 MVA, 13.2kV,xg3=0.15puT1:30 MVA, 6.6Δ−115YkV,xT1=0.10puT2:15 MVA, 6.6Δ−115YkV,xT2=0.10puT3: Single-phase unit each rated 10MVA,6.9/69kV,xT3=0.10pu. Draw per-unit circuit diagram using base values of 30 MVA and 6.6kV in the circuit of generator-1.
