    A voltage transformer for all your 30 kVA, 3 phase applications.

    Some of the most popular 3 phase transformers are 30 kVA 3 phase transformers. Used across a variety of 3 phase power applications, 30 kVA 3 phase transformers are built to withstand the heavy stresses and large electrical loads associated with 3 phase power. 30 kVA 3 phase transformers are used in motor applications, power generation, and other large commercial and industrial applications. While three single phase 10 kVA transformers can be banked together to function as a 3 phase 30 kVA transformer, a single 30 kVA transformer is much more efficient not to mention space saving and easier to install.
