3 Phase Transformer Connection Diagram. To make the transformer connections compatible with three phase supplies we need to connect them together in a particular way to form a three phase transformer configuration. A 10 kva transformer volt secondary is to service an 8 kva.
A 10 kva transformer volt secondary is to service an 8 kva. The dashed lines indicate the transformer outlines. Similarly v bn leads v bn by 30º and v cn leads v cn by 30º this connection is also called 30º connection.
Y y y y and.
In the case of mixed connections the ratio between the main voltages on the primary and secondary sides is not equal to the ratio between the number of turns. The four basic connections are. When you make use of your finger or perhaps stick to the circuit with your eyes it may be easy to mistrace the circuit. The dashed lines indicate the transformer outlines.
