Electric power distribution

OverviewHistoryGeneration and transmissionPrimary distributionSecondary distributionModern distribution systemsSee alsoExternal links

Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. Primary distribution lines carry this medium voltage power to distribution transformers located
