What is a SUBSTATION ?
.
These are excellent
questions!
Let’s deal with them one at a
time.
What is a substation? … what does it do?
… how does it work?
but first....
What is a voltage? (Only 1st 6
minutes of the video is necessary)
Voltage is the measure of force in an electric current.
.
Electricity is transported at a
very high, powerful
voltages. A substation safely
changes the electricity from
very high voltage to lower voltage
we can use.
What does a substation do?
.
Water comes from the water plant in very big pipes, yet
it comes out in your kitchen
or bathroom in much smaller
pipes.
Think of it like a connector for different sized water pipes.
What is a substation?
.
Substations have HUGE
power poles to bring in the high
voltage electricity.
How does a substation work?
.
The substation then takes
electricity from a very high voltage and
lowers it to the voltage we use in our homes &
businesses.
What is a substation?
7
.
Substations are have complex circuit
breakers, switches,
relays, capacitors,
and transformers.
How does a substation work?
.
Transformers ‘step down’ the electricity from the high voltage
needed to economically transmit the electricity.
How does a substation work?
.
There are detectors for fire and line
breaks.
There is automatic fire suppression.
How does a substation work?
A quick picture of how substation works
Can a substation harm me?. The short
answer is YES!
That’s why there are
fences around them. They
can electrocute
people.
.
We need them to cheaply transfer
electricity. Substations are a part of what
we call essential infrastructure.
So why do we have substations?
Essential Infrastructure
Streets &
highways
Radio, cell phone &
microwave towers
Railroads & bridges
Pipelines for natural gas &
other chemicals
Water & wastewater treatment plants
How would you...
explain the need for substations to a 6 year old?
demonstrate what a substation does?
describe how voltages need to be changed for use to use it safely?
