1 A 37.5-KVA, 6900-230-V, 60-Hz, 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 0.0224 and 0.0876 , respectively. The magnetizing reactance and equivalent core-loss resistance (high side) are 43,617 2 and 174,864 , re- spectively. Determine (a) the output voltage when the load is removed; (b) the voltage regulation: (c) the combined input impedance of transformer and load; (d) the exciting current and input impedance at no load. 500
