Final answer:
To calculate the primary and secondary resistances and reactances, multiply the per unit values with the base impedance. For the magnetizing inductance, take the square root of the square of the per unit magnetizing impedance multiplied by the base impedance.
Step-by-step explanation:
The primary and secondary resistances and reactances for a 15-kV:175-kV, 125-MVA, 60-Hz single-phase transformer can be calculated using the given impedance values. The primary resistance (R1) and reactance (X1) can be found by multiplying the per unit values with the base impedance of the transformer. Similarly, the secondary resistance (R2) and reactance (X2) can be calculated using the per unit values and base impedance. The magnetizing inductance can be determined by taking the square root of the square of the per unit magnetizing impedance multiplied by the base impedance.
Primary resistance (R1) = 0.0095 * base impedance
Primary reactance (X1) = 0.063 * base impedance
Secondary resistance (R2) = 0.0095 * base impedance
Secondary reactance (X2) = 0.063 * base impedance
Magnetizing inductance = sqrt((0.148 * base impedance) ^ 2)
Substituting the given base impedance values, we can calculate the primary and secondary resistances and reactances, as well as the magnetizing inductance in ohms and henrys.
