Let the alternator of Problem 4.2.2 supply a line current of 20 A at a power factor of 0.8 lagging. Determine:
(a) The kVA supplied by the machine.
(b) The real power kW delivered by the generator.
(c) The reactive power kVAR delivered by the alternator.
Problem 4.2.2
Consider a three-phase 25-kVA, 440-V, 60-Hz alternator operating at full load (i.e., delivering its rated kVA) under balanced steady-state conditions. Find the magnitudes of the alternator line current and phase current.
(a) If the generator windings are wye-connected.
(b) If the generator windings are delta-connected.
