) For a 50 Hz, 1000 kVA, 11kV/380V three-phase transformer, the short-circuit test carried out at the high voltage side (with the low voltage side short-circuited) has a multi-wattmeter reading of 18 kW and a voltmeter reading of 660 volts (line-to-line) when the input current is at rated level. Estimate: (i) The equivalent impedance of the transformer referred to high voltage side and low voltage side, respectively; (ii) The voltage regulation of the transformer at a load power factor of 0.80 lagging.
