Three single phase transformers with a turns ratio of 1:1 are connected to form a three phase transformer. The transformer input is a three wire three phase 120V (line-to-line) system. the transformer output supplies a "Y" connected three phase load with a phase impedance of 600 + j300 ohms. A. sketch the diagram of the system described above. B . For each of the transformer configurations in the table below, find the phase voltage, and phase current at the load, and the input power (real power) supplied by the source.
