Calculate direct & quadrature axis component of armature current for a 3 phase star connected synchronous generator.
Q. A 3 phase star connected synchronous generator having direct axis reactance of 8 ohm and quadrature axis reactance of 6 ohm supplies current of 9 A with phase angle of 20 degree lagging at 415 V. Then its direct axis component of armature current and quadrature axis component of armature current are- Published on 29 Oct 15a. 8.04 A, 4.04 A
