Electrical Engineering

A three-phase balanced star load No. 1 of (120 +j90) ohms inparallel with another three-phase balanced star load No. 2 of (90+j120) ohms, both are fed by three-phase balanced conductors of 3ohms resistance and 4 ohms reactance. If the generator is 240volts, with angle of -150° on phase c and reactance of 1 ohms,determine: a) the current on load N°1 on phase C, b) the terminalvoltage of the generator on phase B, c) the voltage on load N°2 onphase A and d) the efficiency of the conductors.
