In a balanced three-phase circuit the phase voltage magnitude is VP 277Vrms. For a positive phase

In a balanced three-phase circuit the phase voltage magnitude is VP ¼ 277VðrmsÞ. For a positive phase sequence:

(a) Find all of the line and phase voltage phasors using VAN as the phase reference.

(b) Sketch a phasor diagram of the line and phase voltages.
