Our Professional Answer: Electricity distribution is the vital final stage of power delivery, responsible for carrying electricity from regional substations to individual consumers. After electricity has traveled long distances at high voltages through the transmission grid, it arrives at a distribution substation. Here, transformers "step down" the voltage to lower, safer levels (typically 2 kV to 33 kV). This medium-voltage electricity is then sent out through a network of primary distribution lines. These lines lead to local distribution transformers, which further reduce the voltage to levels usable by homes and businesses (e.g., 120/240V). From these local transformers, power is delivered directly to the end user. This entire network of lines, transformers, and equipment is what we call the electricity distribution system.
