Question: Prob. 4: Consider the following three phase source voltages. v, = 220/2 sin(ot) V, vo = 220/2 sin(@t 120) V, v. = 220/2 sin(mt +120)

Prob. 4: Consider the following three phase

Prob. 4: Consider the following three phase source voltages. v, = 220/2 sin(ot) V, vo = 220/2 sin(@t 120) V, v. = 220/2 sin(mt +120) V where o = 100 a rad/sec. The source supplies a three-phase load such that it draws the following currents. i, = 10/2 sin(mt 30) A, i, = 5/2 sin(@t 150) A, v. = 15/2 sin(ot +120) A (i) Assuming the above voltages and currents under steady state, determine the phasor symmetrical components of voltages and currents and also determine both the active and reactive power delivered. (ii) Assuming the instantaneous voltages and currents as above, determine the instantaneous symmetrical components of voltages and currents. Draw the loci of both voltage and currents. (iii) Determine the instantaneous three-phase real and reactive power and plot them
