A 10, 200 kVA, 2100/210 V, 60 Hz transformer has the following characteristics. The impedance of the high-voltage winding is 0.25 +j1.5 2 with the low-voltage winding short-circuited. The admittance (i.e., inverse of impedance) of the low-voltage winding is 0.025-j0.075 mhos with the high-voltage winding open-circuited. (a) Taking the transformer rating as base, determine the base values of power, voltage, current, and impedance for both the high-voltage and low-voltage sides of the transformer. (b) (c) Determine the per-unit value of the excitation current at rated voltage. (d) Determine the per-unit value of the total power loss in the transformer at full-load output condition. Determine the per-unit value of the equivalent resistance and leakage reactance of the transformer. A 10, 200 kVA, 2100/210 V, 60 Hz transformer has the following characteristics.
