Under the condition for 3 phase alternator, maximum active power output, the delivered reactive power output is ________ while under maximum reactive power output, the delivered reactive power is ________

Correct Answer: negative, negative
Under both the situation, there is need of reactive power which will set up the flux in the machine to make it run.

The active power delivered by an alternator will _______ when the prime mover input is increased for the alternator connected to infinite bus bar.

Under the conditions of maximum reactive power output, the reactive power flowing out of an alternator is __________

The iron losses in a saturated three phase alternator is lesser than the non-saturated three phase alternator.

A system consists of an alternator having reactance of 0.5pu connected to an infinite bus through a series of reactance of 1 pu. The generator terminal voltage of IBB is 1 pu and that of 1.2 pu. The emf induced in the alternator will have the phase difference with respect to reference for the maximum power transfer is _______________

The reactive power flow is outward from an alternator, then the alternator works at ____________

The armature winding of a 2-pole, 3-phase alternator for each phase is distributed in a number of slots per phase. The RMS value of the voltage per phase is less than the RMS value of the voltage per coil multiplied by the number of coils in series because the _________

A 3-phase bridge converter is given a three-phase supply in the phase sequence R-Y-B. Let the neutral to R phase voltage be Vm sinωt. The first SCR (connected to R phase) is fired at an angle of 15°. What is the maximum value at the output terminals at this instant?

Under the condition of maximum power delivered, reactive power is __________

Under the conditions of maximum values of active or reactive power, a synchronous machine always absorbs reactive power.

From the figure shown below for the OCC and SCC of a three phase alternator, the point ‘L’ corresponds to _______ and the point ‘A’ can be obtained by _____ the alternator.
