Electrical Power Systems provides comprehensive, foundational content for a wide range of topics in power system operation and control. Electric power distribution is the final stage in the delivery of electricity. It generally consists of feeders, distributors and the service mains. Generally, a distribution system is the What is electric power distribution? 3 • Electric power distribution is the portion of the power delivery infrastructure that takes the electricity from the highly meshed, high-voltage transmission circuits and delivers it to customers. DISTRIBUTION SYSTEM The arrangement of conveying electric power from bulk power sources (generating stations or major substations) to the various consumers is called distribution system. In general terms, a distribution system is an electricity network station between the substation which it gets from the transmission system and the consumer’s meters. Electrical substations receive high-voltage electricity from the transmission system and step it down to power distribution networks. Huda, R.
