A three-phase synchronous generator (Delta-connected) rated at 10KVA, 230 V, has a synchronous reactance of 1.2ohms per phase and an armature resistance of 0.5ohms per phase. (a) Draw the phasor diagram. (b) Using the phasor diagram, find the internal voltage generated by the generator (per phase) for a 0.8 lagging power factor. (c) Find the voltage regulation (per phase). The voltage regulation is given by:
VR=((Ea-Vphi)/Vphi) *100%
