About Distribution Transformers
Distribution transformers are pole-type transformers that supply relatively small amounts of power to residences. They are used at the end of an electrical utility’s delivery system. Both single-phase and three-phase products are available. Performance specifications for distribution transformers include primary frequency and maximum primary voltage rating. The primary frequency is measured in Hertz (Hz) and indicates the frequency of incoming voltage signals to primaries. Choices include 50 Hz, 60 Hz, 50 and 60 Hz, and 400 Hz. Typically, 400 Hz distribution transformers are designed for aerospace and military applications. Products with other frequency options may also be available. The maximum primary voltage rating is measured in volts (V) and represents a maximum value for devices that use several nominal voltages.
