3 Wire Transformer Wiring Diagram. Hi friends welcome to simple homemade projects in this video i had shown you that how you can use a 3 wire transformer. So that the consumer can use the tansformer for the rated output voltage as well as half of output voltage.
The connection diagram of the three phase star connection is shown in the figure below. These are called center tapped transformers. As stated earlier the lines in a 3 phase transformer wiring diagram represents wires.
The center wire is given for the convenience of the consumer.
The transformers you will be likely to obtain will be the twin 115v primary winding versions. Wiring diagram sheets detail. 12 2 2 anfc 4 2 12 bnfc x4 x1 h10 h2 h3 h1 x2. In this lecture well examine transformer winding polarity transformer power ratings rated voltage rated current parallel winding configurations series.
