A 2.2 kVA, 440/220 V, 50 Hz, step-down transformer has the following parameters referred to the primary side : Re₁ = 3 ohms, Xe₁ = 4 ohms, Rc₁ = 2.5K ohms and Xml = 2Kohms. The transformer is operating at full-load with a power-factor of 0.707 lagging. Determine the voltage regulation of the transformer.
