1 A single phase AC system Consider a single phase AC distribution system in which there a single home connected to a 10kVA service transformer. Let’s assume that the primary of the distribution transformer can be modeled as an ideal 240V (rms) AC source and that the effective impedance of the transformer is 2% resistance and 3% reactance. (See lecture notes for converting % to Ohms). Connected to the secondary of the transformer is 200 ft of #6 AWG aluminum...
