Calculate the Per-Unit Source Voltages
November 8th, 2022
Three zones of a single-phase circuit are identified in the attached figure 3.10(a) {see attachment}. The zones are connected by two transformers, T1 and T1, whose ratings are also shown in the same figure. Using the base values 20 kVa and 115 volts in zone 3, calculate the per-unit source voltage. Neglect the transformer winding resistances and the shunt admittance breaches.
**Please see the attachment for the figure and multiple choice answers.
