Hey, if any1 can help me with this question i would be very grateful.

Im given:

Va=155.56sin(376.991t)
Vb=155.56sin(376.991t-2(pi)/3)
Vc=155.56sin(376.991t-4(pi)/3)

And i have to find:

(a) The operating frequency of the generator.
(b)The peak and rms vaules of the winding voltages.
(c)The phase and line rms voltages if the windings are star-connected.
(d)The phase and line rms voltages if the windings are delta-connected.

I cant seem to find any formulas on the net to help.

Thanks

Matt
