The Electric System
There are various components that are needed to create, transmit, and distribute electricity. The following graphic identifies and describes those various components.
#1 Electricity is generated at one of the many different power plants located throughout the region.
#2 Electricity travels from the power plant over high-voltage transmission lines to substations.
#3 At a substation, the electricity voltage is lowered so that it can travel over the distribution system.
#4 Transformers, both aerial and underground, reduce the electricity voltage even further so it can be accepted by the home or business.
#5 Service lines carry electricity to the home or business.
