A single-phase 50-kVA, 2400/240-volt, 60-Hz distribution transformer has a 1-ohm equivalent leakage reactance and a 5000-ohm magnetizing reactance referred to the high-voltage side.
If rated voltage is applied to the high-voltage winding, calculate the open-circuit secondary voltage. Neglect I2 R and G2 cV losses.
Assume equal series leakage reactances for the primary and the referred secondary. Using the transformer ratings as base quantities in per unit.
