Two 3-phase, Y-connected alternators are to be paralleled to a set of

Two 3-phase, Y-connected alternators are to be paralleled to a set of common busbars. The armature has a per phase synchronous reactance of 1.7 2 and negligible armature resistance. The line voltage of the first machine is adjusted to 3300 V and that of the second machine is adjusted to 3200 V. The machine voltages are in phase at the instant they are paralleled. Under this condition, the synchronizing current per phase will be (A) 16.98 A (C) 33.96 A (B) 29.41 A (D) 58.82 A
