What will be the rms value of emf induced per phase in 3-phase, 6-pole, star-connected alternator having a stator with 90 slots and 8 conductors per slot? The flux per pole is 4 × 10−2 Wb and it runs at a speed of 1000 rpm. Assume full-pitched coils and sinusoidal flux distribution.
- 4.
A three-phase, star-connected, 10 kVA, 230 V alternator has an armature resistance of 0.5 Ω per phase and a synchronous reactance of 1.2 Ω per phase. Calculate the percent voltage regulation at full load at power factors of (a) 0.8 lagging, (b) 0.8 leading, (c) Determine the power factor such that the voltage regulation becomes zero on full load.
