Question: A three-phase (25-mathrm{kVA}, 480-mathrm{V}, 60-mathrm{Hz}) alternator, operating under balanced steady-state conditions, supplies a line current of (20 mathrm{~A}) per phase at a 0.8 lagging power

A three-phase $25-\mathrm{kVA}, 480-\mathrm{V}, 60-\mathrm{Hz}$ alternator, operating under balanced steady-state conditions, supplies a line current of $20 \mathrm{~A}$ per phase at a 0.8 lagging power factor and at rated voltage. Determine the power triangle for this operating condition.
