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.
Electric power distribution become necessary only in the 1880s, when electricity started being generated at . Until then, electricity was usually generated where it was used. The first power-distribution.
Primary distribution voltages range from 4 kV to 35 kV phase-to-phase (2.4 kV to 20 kV phase-to-neutral)Only large consumers are fed directly from distribution voltages; most utility customers are connected to a transformer, which reduces the.
Traditionally, the distribution systems would only operate as simple distribution lines where the electricity from thewould be shared among the customers. Today's distribution systems are heavily integrated withgenerations.

The distribution grid is so large in comparison to most loads that it appears to be infinite, not only visually, but in most calculations as well. If a load took 100 A on each phase in a 400/230 V three-phase system, most apprentices would consider this a large load; however, a relatively small 500 MW power station can supply over 100,000 A per phase at 230 V.
What is a Distribution System? The part of the power system that distributes electric power for local use is called as distribution system.
