Three Transformer Diagram. In the diagram below is shown a three phase transformer basic designthe transformer has three limbs. As stated earlier the lines in a 3 phase transformer wiring diagram represents wires.
For the system shown in figure 4 draw the electric circuit or reactance diagram with all reactances marked in per unit pu values and find the generator terminal voltage assuming both motors operating at 12 kv three quarters load and unity power factor. A three phase transformer consists of two three phase windings. The efficiency of a transformer is the ratio of the power it delivers to.

A three phase transformer consists of two three phase windings. Each phase winding is wound around one of the limbs. Practically almost every electrical power system deals with three phase power. As stated earlier the lines in a 3 phase transformer wiring diagram represents wires.
