The voltage rating of a distribution transformer can vary depending on the specific application and the electrical grid's requirements. However, typically, distribution transformers are designed to step down the voltage from higher primary distribution levels to lower secondary levels suitable for residential, commercial, or light industrial use.
In many systems, the primary voltage side of a distribution transformer might be in the range of 3.3 kV, 6.6 kV, 11 kV, 15kV, 20kV or up to 33 kV. The secondary voltage, which is the output side, is usually transformed down to either 230V (single-phase) or 400V (three-phase) for low voltage distribution networks. In North America, the common household voltage is 120V/240V single-phase, derived from a 7200V or 12470V primary distribution network through a transformer.
It's important to note that these voltages are general guidelines and can differ based on regional standards, system designs, and specific utility configurations. Always refer to our specifications for the exact voltage ratings of a given distribution transformer.
