1) A three-phase, balanced, star-connected load in which each phase consists of an inductance of 0.4 H in series with a resistance of 30 Q2 is connected to a balanced, three-phase 200 V, 50 Hz supply. Calculate (i) the rms line currents in the system and their phase relationship with the supply phase voltage, (ii) the total power dissipated in the three-phase load, and (iii) the total reactive power requirement of the load. The three load impedances are now connected in delta. What is the total load power in this arrangement?
