You have been hired as a consultation engineer for a manufacturing company to test and diagnose a low voltage and overheating problem with a single phase transformer utilized to supply their single phase loads. The company technicians informed you that the transformer has a solid nickel core, insulated aluminum windings and its nameplate ratings are 100 kVA, 6600/230 V, 60 Hz (a) Given that the transformer is delivering 80% full load at 0.9 power factor lag calculate: 1) the output voltage assuming the input voltage is maintained at 6600V n the voltage regulation at this load iIm) the efficiency at this load
