A 37.5-kVA, 6900-230V, 60Hz, single phase transformer is operating in the step down mode at rated load, rated voltage, and 0.68 power factor lagging. The equivalent resistance and reactance referred to the low side are 0.0224Ω and 0.0876Ω, respectively. The magnetizing reactance and equivalent core loss resistance (high side) are 43,617Ω and 174,864Ω, respectively. Determine (a) the output voltage when the load is removed; (b) the voltage regulation: (c)the combined impedance of transformer and load; (d) the exciting current and input impedance at no load.
