UNIT – I

With a neat phasor diagram, explain about the Practical Transformer under Load condition. TUTORIALS The voltage/turn of a 1-Φ transformer is 1.1V, when the primary winding is connected to a 220V, 50Hz ac supply, the secondary voltage is found to be 660V.Find (1) Primary & secondary currents (2) the core area if the maximum flux density is 1.2 T. ................
