in Electric Power and Other Industries

Electric power networks consist of transmission systems and distribution systems. e transmission

system

consists

of

high-voltage

power

lines

and

a

relatively

small

number

of

large

substations.

It

delivers

energy

to

terminal

stations

where

transformers

step

the

voltage

down

and

feed

energy

into

the

distribu-

tion

network.

Distribution

networks

include

large

numbers

of

smaller

substations

and

transformers

that

further

convert

the

power

to

mains

voltages

and

reticulate

this

to

domestic

and

commercial

consumers.

Large

generation

stations

connect

directly

to
