(b) A balanced 200 V, three-phase generator is supply to a balanced delta-connected load. The voltage expression in time domain at the sources are: Vrn(t) = 200 cos(wt + 10°) V Vyn (t) = 200 cos(wt – 230°) V Von(t) = 200 cos(wt – 110°) V (i) Determine the voltages in phasor form. (ii) Draw the phasor diagram of the system and give your comments in word of leading or lagging. (iii) Determine the phase sequence of the set of voltages.

(b) A balanced 200 V, three-phase generator is supply to a balanced delta-connected load. The
voltage expression in time domain at the sources are:
Vrn(t) = 200 cos(wt + 10°) V
Vyn (t) = 200 cos(wt – 230°) V
Von(t) = 200 cos(wt – 110°) V
(i)
Determine the voltages in phasor form.
(ii) Draw the phasor diagram of the system and give your comments in word of leading
or lagging.
(iii) Determine the phase sequence of the set of voltages.
