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.

Jul 30, 1999 · The phasor diagram is an effective tool for visualizing the relationships between internal voltage, armature current, and terminal voltage. The excitation control system is used on synchronous machines to regulate terminal voltage, and the turbine-governor system is used to regulate the speed of the machine.

Also determine the current. Assuming the voltage at Node 1 is at zero degrees (i.e. this will be the reference phasor and will be placed at zero degrees on the phasor diagram), measure the phase angle of the potential at Nodes 2 and 3 and the phase angle of the current. Place the raw data in Table D-3.
