Distribution transformers | Choosing the Right Transformer
There are 5 main types of transformers. The differences between each transformer are related to the types of applications possible. Current transformers: these are transformers in which the secondary current is proportional to the primary current. They can be used with all low-frequency alternating currents. Power transformers: these are distribution transformers with a voltage of one phase higher than 1,000V. They are used to transport electricity over long...

How to choose this product
distribution-transformer

The distribution transformer is part of the electric power distribution network. It steps down the elevated voltage in high-tension lines to levels usable by consumers.

Technologies

These are large devices. They are usually housed in a case filled with inert, non-conductive oil or an inflammable liquid coolant. Such transformers are generally single-phase or three-phase, depending on area.

How to choose

A distribution transformer represents a significant investment. It must last several decades and be relatively inexpensive to maintain. Choice parameters include initial cost, as well as the no-load and impedance losses.

Disadvantages

- Expensive
