Transformers are an integral part of the electrical industry. They convert a high AC voltage to a lower AC voltage or vice versa, without changing the frequency of the signal. One common type of transformer is the Delta Delta transformer, which is often used in electrical power distribution systems due to its distinct advantages.
What is a Delta Delta Transformer?
A Delta Delta transformer is a three-phase transformer that connects three input phases to three output phases in a delta configuration. The transformer consists of three coils that interconnect without a neutral wire. One coil is connected to each of the three input phases (A, B, C) of the system, and each output phase is connected to the junction between two coils.
Because it has no neutral wire, the Delta Delta transformer is a great transformer for large-scale applications that need high load capacity, such as for industrial or commercial uses. Additionally, it is also relatively inexpensive and simple to install, due to its lack of a neutral wire.
Wiring Diagram for Delta Delta Transformer
A Delta Delta transformer wiring diagram is commonly used to connect the three coils in a Delta Delta configuration. In this configuration, each coil is connected to two other coils, forming a triangle-shaped circuit. The primary winding of the transformer is connected in delta and the secondary winding in delta, and all of the coils are connected in series.
The wiring diagram for a Delta Delta transformer is as follows:
| Phases | Primary | Secondary |
|---|---|---|
| A | 1-2 | 1-2 |
| B | 2-3 | 2-3 |
| C | 1-3 | 1-3 |
Note that in the wiring diagram, the primary side and secondary side of the transformer are connected in a delta configuration. The three-phase supply is connected to the primary side of the transformer, and the load is connected to the secondary side.
