    Why use a 3 phase transformer?

    When you’re using a 3 phase supply, it only makes sense to use a 3 phase transformer. These transformers are used to convert the supply voltage from one type to another. They also have isolating capabilities.

    Technically speaking, and when looking at a transformer wiring diagram, it is possible to connect three separate single phase transformers to service a 3 phase supply; however, 3 phase transformers are built specifically for these tasks, and require far less energy, effort, material and money to operate. The most obvious difference between a single phase transformer and a 3 phase transformer are the windings. A 3 phase transformer is composed of three sets of single phase windings together on a single core, and not 3 separate devices connected together.

    When should I use a 3 phase transformer?

    3 phase transformers are used to handle heavy electrical loads. One of the most common usages of 3 phase transformers are motor applications since they can effectively handle the heat, vibration, and voltage of these heavier motor loads. 3 phase transformers are also used throughout industrial and commercial sectors for power generation, motor applications, and any other industry that deals with 3 phase power.
