What is a Substation?As you should know,
electricity is not delivered
straight from the power
stations to the consumers.
It is a subsidiary station of
an electrical system which
uses voltage.

What is a Substation?Most substations are located
outdoors, normally enclosed by
wire fenced and with danger
and no trespassing sings towarn the public to keep away to
avoid high voltage electrical risks.

What is a Substation?In some residential and high
density areas, substations
may be housed inside
building to reduce noise
pollution from the humming
of large transformers.

What is a Substation?Some can even be found at top of buildings.
Substations are managed and operated by certain
level 1 ASP electricians, engineers and operators
who are all substation installation professionals.

The Functions of Substations
Substations are like trains
stations or airports where
people get on and off ships and
airplanes respectively whentravelling to far places. With this
analogy, we can learn how a
substation works.

The Functions of Substations
At substations where the
voltage is transformed from
high to low and vice versa.
Substation engineers use step-up transformers to increase the
voltage to high values.
