Q. Consider an elementary three-phase, four-pole alternator with a wye-connected armature winding, consisting of full-pitch concentrated coils. Each phase
coil has three turns, and all the turns in any one phase are connected in series. The flux per pole, distributed sinusoidally in space, is 0.1 Wb. The rotor is driven at 1800 r/min.
(a) Calculate the rms voltage generated in each phase.
(b) If a voltmeter were connected across the two line terminals, what would it read?
(c) For the a-b-c phase sequence, take t = 0at the instant when the flux linkages with the a-phase are maximum.
(i) Express the three phase voltages as functions of time.
(ii) Draw a corresponding phasor diagram of these voltages with the a-phase voltage as reference.
(iii) Represent the line-to-line voltages on the phasor diagram in part (ii).
A coil has an inductance of 1.2H and a resistance of 40? and is connected to a 200 V, d.c. supply. Verify the approximate value of the current flowing 60 ms after connecting the co
Let the message signal m(t) = α cos (2πf m t) be used to either frequency-modulate or phase- modulate the carrier Ac cos(2πf c t). Find the modulated signal in each case.
