A 2300-V, three-phase, wye-connected, round rotor synchronousmotor has a synchronous reactance of 3 per phase and an armature resistance of 0.25 per phase. The motor operates on load with a power angle of -15°, and the excitation is adjusted so that the internally induced voltage is equal in magnitude to the terminal voltage.
Determine:
(a) The armature current.
(b) The power factor of the motor.
Neglect the effect of armature resistance.
Define the operation of real mode interrupt. Operation of Real mode interrupt: While the microprocessor completes executing the current instruction, this determines whether a
