50 Points 1 - A balanced delta connected load of 15 + j18 12 per phase is connected at the end of a three-phase line as shown in Figure 1. The line impedance is 1 + j2 12 per phase. The line is supplied from a three-phase source with a line-to-line voltage of 207.85 V rms. Taking the phase voltage Van as reference, determine: a) Current in...
