Standard and Common Voltage Levels in the US and CA
600V AC is a common voltage level used for three-phase power distribution in industrial settings. It is typically supplied by a transformer that steps down the distribution voltage, which is typically 7.2k
What are the common voltage levels used in distribution networks?
Common primary distribution voltages include 11kV, 22kV, and 33kV, which are used to carry power from substations to local transformers. After stepping down, secondary voltages like
Primary Distribution Voltage Levels
distribution voltages are between 4 and 35 kV. In this article, unless otherwise specified, voltages are given as line-to-line voltages; this follows normal industry practice, but it is sometimes a source of
