A three-phase Δ-connected generator has an internal impedance of 9+j90 m Ω/ϕ. When the load is removed from the generator, the magnitude of the terminal voltage is 13,800 V. The generator feeds a Δconnected load through a transmission line with an impedance of 20+j180 m Ω/ϕ. The per-phase impedance of the load is 7.056+j3.417  Ω. Construct a single-phase equivalent circuit.
