Three sinnal-phase 50 KVA 2400:240 -volts transformers are connected Y-Δ and supplied with power through a 2400-V (line to line) 3-phase feeder whose reactance is 0.80 Ω/phase. The equivalent reactance of each transformer referred to its high voltage side is 1.82 Ω. All circuit resistances will be neglected. At its sending end the feeder isconnected to the secondary terminals of a 3-phase Y-Δ connected transformer whose 3-phase rating is 600kVA, 24000:2400 V (line to line voltages). The equvalent reactance of the sendin-end transformers is 2.76 Ω / phase Δ referred to the 2400-V side. The voltage applied to the primary terminals is 24000 V line to line.

A 3-phase short circuit occurs at the 240-V terminals of the receiving -end transformers. Compute the steady-state short-circuit current in the 2400-V feeder wires, in the primary and secondary windings of the receving-end transformers, and at the 240 V transformers.
