Question: A balanced three-phase source with the following instantaneous phase voltage = 2500 cos(wr) V = 2500 cos(wr-120) Y = 2500 cos(wt-240) supplies balanced Y-connected

A balanced three-phase source with the following instantaneous phase voltage = 2500

A balanced three-phase source with the following instantaneous phase voltage = 2500 cos(wr) V = 2500 cos(wr-120) Y = 2500 cos(wt-240) supplies balanced Y-connected load of impedance Z=250/36.87 per phase. Calculate: a) The Line-Line voltage (VV) b) The phase current in each lines. c) The total reactive and active power supplied to the loads. d) Power factor angel & power factor.
