Transformers are electrical devices that make it possible to transfer electrical energy from one circuit to another. A delta transformer is a type of transformer that is configured with three windings, making it ideal for use in three-phase power distribution systems. In this article, we will discuss the wiring diagram for a 120 240 volt delta transformer and how it works.
Understanding the Delta Transformer
The delta transformer is a three-phase transformer that is constructed with three windings. These three windings are connected in a delta configuration and they are wound around a magnetic core. The phase voltage of the delta transformer is a function of the line voltage and the square root of three.
This means that the phase voltage of a 120 240 volt delta transformer is 120 volts, while the line voltage is 240 volts. The delta transformer is often used in power distribution systems to convert high voltage, low current electricity into low voltage, high current electricity that can be used by homes and businesses.
Wiring Diagram for a 120 240 Volt Delta Transformer
Below is a simple wiring diagram for a 120 240 volt delta transformer:
| Terminal | Primary 120/240V | Secondary 120/240V |
|---|---|---|
| 1 | X2 | X1 |
| 2 | X3 | X2 |
| 3 | X1 | X3 |
The primary side of the transformer is connected to a 120/240 volt power source, while the secondary side is connected to the load. The X1, X2, and X3 terminals represent the three windings of the delta transformer.
