A 5000-kVA transformer has series impedance of R = 3% and X = 7%. Determine the percentage
Question:
A 5000-kVA transformer has series impedance of R = 3% and X = 7%. Determine the percentage of rise in the output voltage on unloading the transformer from full load at 0.8 pf lagging to zero load, which is also known as the full-load voltage regulation (VR) of the transformer.
