Three single-phase transformers, each rated 15 MVA, 13.2:66 kV, with a leakage reactance of 0.1 pu, are connected to form a three-phase Y-Δ bank, one side of which is connected to a 120-kV tranmission line and the other side, to three 12-ohm resistors in delta. The star point of the transformer bank is grounded. The series reactance per phase of the transmission line is 80Ω.
Draw a single-line diagram of the system and obtain the line to neutral diagram with per-unit values, for a base voltage of 120kV in the transmission line and a three-phase voltampere base of 50 MVA.
