ELECTRICITY TRANSMISSION AND DISTRIBUTION
ELECTRICITY TRANSMISSION AND DISTRIBUTION Path of electricity
from generator stations, transmission stations and residential
areas- Julia Francesca Esperida Carmel Bernadeth Jaylo Edrae

complex system of power generation, transmission systems, and
distribution systems.
MAJOR COMPONENTS OF A ELECTRICAL INFRASTRUCTURE Power Generation
plants
- These are facilities designed to produce electric energy.
Typical power generation plants are fueled by coal, natural gas,
hydroelectric, or nuclear, but can also be solar powered, wind
powered, or geothermal powered.
2. Transmission lines
- Can be hung overhead or underground. Carry electric energy
from one point to another in an electric power system. - The main
characteristics that distinguish transmission lines from
distribution lines are that they are operated at relatively high
voltages, they transmit large quantities of power, and they
transmit the power over large distances.
Substation
- A high-voltage electric system facility. It is used to switch
generators, equipment, and circuits or lines in and out of a
system. Some substations are small with little more than a
transformer and associated switches. Others are very large with
several transformers and dozens of switches and other equipment. -
Substationstransform voltage from high to low, or the reverse, or
perform any of several other important functions.
Distribution System
- Originates at a distribution substation and includes the
lines, poles, transformers and other equipment needed to deliver
electric power to the customer at the required voltages.
