A 3-phase, 230 V, 30 kVA, 0.9 PF(lag) load is supplied by three 10 kVA, 1330/230 V, and 60 Hz transformers connected in YA. The transformers are supplied from a 34 source through a 3p feeder whose impedance is 3+j4 2 per phase. The equivalent impedance of one transformer referred to on the low-voltage side is 0.3+j0.3 02. Determine: The supply voltage if the load voltage is 230 V. The % voltage regulation
