In India Electrecal power is Generated at a voltage
of 11kv to 33kv ,which is taken stepped up to the
transmission level in the range of 66kv to 400kv
member of transmission and switching have to be
created these are known as ”Substation”.
Substation is an assembly of apparatus ,which
transform the characteristics of electrical energy
from one form to another say from one voltage
level to another level. hence a substation is an
Intermediate link between the Generating station
and consumer

Substations have switching, protection and control equipment and one
or more transformers. In a large substation, circuit breaker are used to
interrupt any short-circuits or overload currents that may occur on the
network

220KV KUNDA KI DHANI GRID
SUBSTATION
220kv kunda kidhani, amer is a conventional, hybrid
substation.
It is part of transmission system.
33kv substation is gas insulated substation which is
inside the control room.
 for communication purpose PLCC is used.

LIGHTNING ARRESTOR
 Lightning arrestor provide protection to all the
equipment against the HV.an electric discharge
between cloud and earth ,between cloud and
charge enters of some loud is known as lightning.
 It is provide to safety transmission &distribution
line.

9.
INSULATER
An electrical insulator is
a material whose
internal electric charge
do not flow freely and
therefor make it very
hard to conduct an
electric current under
the influence of an
electric field.

10.
POWER TRANSFORMER
•For stepping up or down the system voltage, power transformers are used in
the substations. At generating end, the voltage is only stepped up for
transmission of power while at all the subsequent substations the voltage is
gradually stepped down to reach finally to working voltage level

11.
CURRENT TRANSFORMER
The current
transformer are used to
stepped down .
It is used to
measurement/control/
protection.

12.
CIRCUIT BREAKER
 Circuit breaker are used for
switching and protection.
 Brake a circuit and
automatically under fault
condition.
 A circuit breaker consist of
fixed and moving contact
called electrode under
normal condition.

13.
BUSBARS
 Bus bars are common
electrical component
through which a
large no. of feeders
operating at some
voltage have to
connected.
 It is used to connect
to transmission line
which go to
electricity.
 It is used to high
material conductor.

14.
PROTECTIVE REALAY
 A Protective relay is a
device which detect
the fault.
 It is to detect after
their go to command
circuit breaker
 It is provide to safety
in electrical
equipments.

3. 220kv (Broun)
4. 440kv (indigo)
5. 110kv (orange)

17.
POTENTIAL TRANSFORMER
The potential transformer is used to one electrical
form to another form .
It is used to measurement of current &voltage.

CONCLUSION
 An Engineer need to have not just theoretical but
practical as well as and so every student is supposed to
under go a practical training .session after 3rd year
where I have impaired the knowledge about
transmission ,distribution .during the 60 days training
session. we have acquainted with the repairing of a
transformer and testing of transformer. At last is
would like to say that practical training taken at 220kv
gss , kunda ki dhani, amer has broadened my knowledge
and widened my thinking as a professional.
