A 5-k VA, 220-V, 60-Hz, six-pole, Y-connected synchronous generator has a leakage reactance per phase of 0.78 ohms and negligible armature resistance. The armature-reaction EMF for this machine is related to the armature current by
![]()
Assume that the generated EMF is related to field current by
![]()
A. Compute the field current required to establish rated voltage across the terminals of a unity power factor load that draws rated generator armature current.
B. Determine the field current needed to provide rated terminal voltage to a load that draws 125 percent of rated current at 0.8 PF lagging.
