Conversation so far:
what is electric power generation transmission and distribution
There are three stages of electric power supply; generation, transmission and distribution. Each of these stages involves distinct production processes, work activities and hazards.
at how many volts is electric power generated
Most electricity is generated at 13,200 to 24,000 volts.
where are transmission lines constructed
Transmission lines are constructed between transmission substations located at electric generating stations.

Question: what does the distribution system do
