High Voltage is stepped down at substations to medium voltage (MV) of approximately 7,200 volts by transformers for transmission over distribution networks.Transformers in proximity to the subscribers’ premises step that voltage down further to low voltage (LV) of 110 volts (or 205 or 220 volts) in North America, and 220 volts in Europe and most of the rest of the world.
