3. Definition of sub-station
A substation is a part of an electrical generation, transmission,
and distribution system.
The assembly of apparatus used to change some characteristic
of electric supply is called a sub-station
6. Working of sub- station
• Electrical power is transmitted at high voltage using
transmission line and brought to the placed of utilization.
• But the power is not utilized at high voltage. For this it is
converted to the required form and voltage.
• This is because power is utilized in different forms and at
different voltages.
• In big industries power is delivered at 11kv. For domestic use
230v a.c. supply.

17. Application of Sub-Station
we know the electrical power is generated at around 11kv
and this voltage is stepped up to high voltage and brought to
the place of utilization.
Now electrical power is not used at this high voltage.
So this high voltage is stepped down to the required voltage
and power is distributed in different area.
This task is performed by using sub-station. In this unit ,we
shall obtain information about different type of substation .
