About the 480-240 Volt 3 Phase Electrical Transformer-6

The 480-240 Volt 3 Phase Transformer-6 is equipped with an electrostatic shield and windings to meet the requirements of your unique application. The 3 phase electrical transformers are safe and efficient to use in commercial environments. The 480-240 Volt 3 Phase Electrical Transformer-6 features a 60 Hz rating and a Seismic Zone IV Compliant certification.

How a Three Phase Transformer Operates

3 phase electric transformers feature 3 interchanging voltages that vary in phase by 120 degrees. The 480-240 Volt 3 Phase Transformer-6 is equipped with a total of 3 single phase windings that are integrated with a single core. The output of this type of transformer is able to be produced by configuring an individual 3 phase transformer or by connecting 3 single phase transformers. 

A majority of organizations decide to invest in a single 3 phase transformer instead of 3 separate single phase transformers because they feature a compact design and are easier to install. In addition, the copper and iron cores are more efficient with a 3 phase transformer configuration. The primary and secondary windings of a 3 phase power transformer are engineered to be integrated in various configurations to meet the requirements of your application.

Types of Transformer Connections

The 3 types of integrations that can be created by the 480-240 Volt 3 Phase Electric Transformer-6 are Wye (Star), Zig-Zag (Interconnected Star), and Mesh (Delta). A 3 phase power transformer features a total of 3 primary and secondary windings that are designed to be connected in a variety of ways. The windings can be integrated to resemble Delta or Star shapes. To determine the correct type of connection, you will be required to inspect the 3 voltages that are separated by 120 degrees.

To ensure your configuration is organized correctly, it’s important to assign letters to the 3 primary windings on a 3 phase electrical transformer. Letters such as A, B, and C are utilized to identify various types of phases including Red, Yellow, and Blue. Always use uppercase letters to identify the primary windings of a transformer. On the other hand, the secondary windings of a 3 phase transformer are identified with the lowercase letters a, b, and c.

Transformers Are Designed to Modify Voltage Levels

The 480-240 Volt 3 Phase Transformer-6 is engineered to circulate electricity to 3 phase systems such as electric motors. Electric transformers are constructed to modify voltage levels before the electricity reaches its destination, such as a piece of hardware or a motor in a warehouse. 3 phase electrical transformers are utilized by operators to boost or decrease voltage that is being distributed to hardware. If a transformer is used to increase the voltage, the increase is referred to as stepping up the voltage. On the other hand, a transformer that is utilized to decrease voltage levels is referred to as stepping down the voltage.
