A three-phase, 50-hp, 460-V, letter code-G induction motor is connected to 480 VLL lines via a transformer with 0.034 + j 0.097 Ω/ph impedance and cable with 0.006 + j 0.003 Ω/ph in series. Assuming the locked rotor power factor 0.20, determine the percentage of voltage drop on start with and without the Y–Δ starter.
